This series contains a bunch of minor improvements to the driver. I have
another bunch waiting with more major changes.

Most of the changes are quite straightforward, and the only patches of note are
as follows:
- Fix the command abort feature, enabled with host option SDEBUG_OPT_CMD_ABORT
- Drop driver count of queued commands per device
- Add poll mode completions to statistics. We already have poll mode callback
  call count, so maybe it was intentional to omit poll mode from the
  statistics.
  
Based on scsi-staging 6.4 @ commit ffba85603c62 ("Merge patch series "lpfc: Update lpfc to revision 14.2.0.11")
