The QP transition optional parameters for the various transition for XRC
QPs are identical to those for RC QPs.

Many of the XRC QP transition optional parameter bits are missing from the
QP optional mask table.  These omissions caused failures when doing XRC QP
state transitions.

For example, when trying to change the response timer of an XRC receive QP
via the RTS2RTS transition, the new timer value was ignored because
MLX5_QP_OPTPAR_RNR_TIMEOUT bit was missing from the optional params mask
for XRC qps for the RTS2RTS transition.

Fix this by adding the missing XRC optional parameters for all QP
transitions to the opt_mask table.

The flag update_cur_sg tracks whether contiguous pages from a new set of
page_list pages can be merged into the SGE passed into
ib_umem_add_sg_table(). If this flag is true, but the total segment length
exceeds the max_seg_size supported by HW, we avoid combining to this SGE
and move to a new SGE (x) and merge 'len' pages to it. However, if i <
npages, the next iteration can incorrectly merge 'len' contiguous pages
into x instead of into a new SGE since update_cur_sg is still true.

Reset update_cur_sg to false always after the check to merge pages into
the first SGE passed in to ib_umem_add_sg_table().  Also, prevent a new
SGE's segment length from ever exceeding HW max_seg_sz.

 * BAR pages intended for read-only can be switched to writable via mprotect.
 * Missing use of rdma_user_mmap_io for the mlx5 clock BAR page.
 * Disassociate causes SIGBUS when touching the pages.
 * CPU pages are being mapped through to the process via remap_pfn_range

When this code was consolidated the intention was that the VMA would
become backed by anonymous zero pages after the zap_vma_pte - however this
very subtly relied on setting the vm_ops = NULL and clearing the VM_SHARED
bits to transform the VMA into an anonymous VMA. Since the vm_ops was
removed this broke.

Now userspace gets a SIGBUS if it touches the vma after disassociation.

Instead of converting the VMA to anonymous provide a fault handler that
puts a zero'd page into the VMA when user-space touches it after
disassociation.

When working in mutliport RoCE mode it is possible to attach a slave
before the master. In that case the slave is waiting for a master to be
attached.  When the master is attached it goes over the list of waiting
slaves, finds a slave that is compatible and tries to bind it to itself.

The call stack is:
mlx5_ib_init_multiport_master() -> mlx5_ib_bind_slave_port()

In the bind function we will create a netdev notifier, but this is done
before we initialize the RoCE structure (this is done at a later stage by
the master in the ROCE stage).

Once events are delivered to that notifier we will use
mlx5_ib_get_native_port_mdev() to get the actual port and as the native
port is zero we will access an invalid index in the port structure.

Move the RoCE structure initialization to an earlier stage.
