Currently the slave and master resources are deleted after master freed
all bitmaps. If any resources were not properly cleaned up during the
shutdown process, an Oops would result.

Fix so that delete slave (only) resources during cleanup. Master resources
are cleaned up during unload process, and need not separately be cleaned.

Note that during cleanup, we need to split the resource-tracker freeing
functionality.

Before removing all the bitmaps, we free any leftover slave resources.
However, we can only remove the resource tracker linked list after
all bitmap frees, since some of the freeing functions (e.g.,
mlx4_cleanup_eq_table) use paravirtualized FW commands which expect
the resource tracker linked list to be present.

Consider the following scenario: 2 HCAs, where only one of which can run SRIOV.

If we reset the module parameter, all the VFs of the SRIOV HCA will be
claimed by the PPF host (-- the code relies on num_vfs being non-zero
to avoid this claiming, and num_vfs was reset when pci_enable_sriov failed
for the non-SRIOV HCA).

The solution is not to touch the num_vfs parameter.

Also, eliminate the unneeded check of num_vfs when disabling sriov
(the dev flag bit is sufficient).

In function mlx4_INIT_PORT_wrapper, the port state mask for the
slave is only set if we are invoking the INIT_PORT fw command.

However, the reference count for the (initialized) port is
incremented anyway.

This creates a problem in that when we have multiple slaves,
then the CLOSE_PORT command will never be invoked. The
reason is that in the CLOSE_PORT wrapper, if the port-state
mask is zero for the slave (which it is), the wrapper returns
without doing anything. The only slave which will not return
immediately in the CLOSE_PORT wrapper is that slave for which
INIT_PORT was invoked.

The fix is to not have the port-state mask setting depend
on the logic for calling the INIT_PORT fw command.

__ratelimit() can be considered an inverted bool test because
it returns true when not ratelimited.  Several tests in the
kernel tree use this __ratelimit() function incorrectly.

No net_ratelimit uses are incorrect currently though.

Most uses of net_ratelimit are to log something via printk or
pr_<level>.

In order to minimize the uses of net_ratelimit, and to start
standardizing the code style used for __ratelimit() and net_ratelimit(),
add a net_ratelimited_function() macro and net_<level>_ratelimited()
logging macros similar to pr_<level>_ratelimited that use the global
net_ratelimit instead of a static per call site "struct ratelimit_state".

In case of a client X roaming from a generic node A to another node B, it is
possible that a third node C gets A's OGM but not B's. At this point in time, if
C wants to send data to X it will send a unicast packet destined to A. The
packet header will contain A's last ttvn (C got A's OGM and so it knows it).

The packet will travel towards A without being intercepted because the ttvn
contained in its header is the newest for A.

Once A will receive the packet, A's state will not report to be in a "roaming
phase" (because, after a roaming, once A sends out its OGM, all the changes are
committed and the node is considered not to be in the roaming state anymore)
and it will match the ttvn carried by the packet. Therefore there is no reason
for A to try to alter the packet's route, thus dropping the packet because the
destination client is not there anymore.

However, C is well aware that it's routing information towards the client X is
outdated as it received an OGM from A saying that the client roamed away.
Thanks to this detail, this patch introduces a small change in behaviour: as
long as C is in the state of not knowing the new location of client X it will
forward the traffic to its last known location using ttvn-1 of the destination.
By using an older ttvn node A will be forced to re-route the packet.
Intermediate nodes are also allowed to update the packet's destination as long
as they have the information about the client's new location.
