The mempool_destroy() function tests whether its argument is NULL
and then returns immediately. Thus the test around the calls is not needed.
This issue was detected by using the Coccinelle software.

Modularize, cleanup, add comments - for FDMI code in driver
Note: I don't like the comments with leading # - but as we have a lot if
present, I'm deferring to handle it in one big fix later.

Fix the FLOGI discovery logic to comply with T11 standards
We weren't properly setting fabric parameters, such as R_A_TOV and E_D_TOV,
when we registered the vfi object in default configs and pt2pt configs.
Revise to now pass service params with the values to the firmware and
ensure they are reset on link bounce. Required reworking the call sequence
in the discovery threads.

This patch changes the !blk-mq path to the same defaults as the blk-mq
I/O path by always enabling block tagging, and always using host wide
tags. We've had blk-mq available for a few releases so bugs with
this mode should have been ironed out, and this ensures we get better
coverage of over tagging setup over different configs.

kmalloc() can return NULL and without checking we were dereferencing it.
Moreover if kmalloc succeeds but the function fails in other parts then
we were returning the error code but we missed freeing lcb_context.
While at it fixed one related checkpatch warning.

Fix for discovery failure in PT2PT when FLOGI's ELS ACC response gets aborted
Change login state machine to:
- Restart FLOGI if prior is ABTS'd
- Reject incoming FLOGIs if we have one pending
The above ensures that we always finish FLOGI processing, regardless
of who initated FLOGI, before processing PLOGI's.

lpfc_send_rscn_event() allocates data for sizeof(struct
lpfc_rscn_event_header) + payload_len, but claims that the data has size
of sizeof(struct lpfc_els_event_header) + payload_len. That leads to
buffer overruns.
