AM53C974A's Start Transfer Counter register has 24 bits, thus
maximum transfer length is 16MiB. But the maximum I can test
is 8MiB, so use that until somebody tests 16MiB.

The error path path mistakenly called sysfs_create_group() rather than

- fix: toshoboe_invalid_dev() was recently removed, but not all callers
  were updated, causing the obvious linker error.  Remove caller,
  because the check (like the one removed) isn't used.

- fix: propagate request_irq() return value

- cleanup: remove void* casts

- cleanup: remove impossible ASSERTs

Since pr_debug() has changed from a macro to an inline function when
DEBUG is not defined, its arguments now need to be defined even when
debugging is off.  Therefore to_event_str() and to_qp_state_str() need
to be moved out of #ifdef DEBUG.  The compiler will throw the
definitions away if DEBUG is not defined, but it needs to be able to
see that the functions exist.

Currently a DREP is only sent in response to a DREQ if a connection
has been found matching the DREQ, and it is in the proper state.  Once
a DREP is sent, the local connection moves into timewait.  Duplicate
DREQs received while in this state result in re-sending the DREP.

However, it's likely that the local connection will enter and exit
timewait before the remote side times out a lost DREP and resends a DREQ.
To handle this, we send a DREP in response to a DREQ, even if a local
connection is not found.  This avoids maintaining disconnected
id's in timewait states for excessively long times, just to handle a
lost DREP.

If the ib_cm module is unloaded while id's are still in timewait, the
CM will destroy the work queue used to process timewait.  Once the
id's exit timewait, their timers will fire, leading to a crash trying
to access the destroyed work queue.

We need to track id's that are in timewait, and cancel their deferred
work on module unload.

Enable multiple concurrent connections to the same SRP target:

1) Use port GUID instead of node GUID in the initiator port
   identifier.  This allows connections to be made from multiple HCA
   ports at the same time.
2) Let the user specify the identifier extention when adding the
   device.  This allows userspace to make multiple connections even
   from the same port, if it wants too.

Without this, only one connection can be made from any given HCA, even
if it has multiple ports, because we don't use multi-channel mode, so
targets will only allow one connection from a given initiator port ID.
