    Multiple Discovery Fixes:
    - Fix race on discovery due to link events coinciding with vport_delete.
    - Use NLP_FABRIC state to filter out switch-based pseudo initiators that
       reuse the same WWNs.
    - Correct erroneous setting of DID=0 in lpfc_matchdid()
    - Correct extra reference count that was in the lookup path for the
      remoteid from an unsolicited ELS.
    - Correct double-free bug in els abort path.
    - Correct FDMI server discovery logic for switch that return a WWN of 0.
    - Fix bugs in ndlp mgmt when a node changes address
    - Correct bug that did not delete RSCNs for vports upon link transitions
    - Fix "0216 Link event during NS query" error which pops up when vports
      are swapped to different switch ports.
    - Add sanity checks on ndlp structures
    - Fix devloss log message to dump WWN correctly
    - Hold off mgmt commands that were interferring with discovery mailbox cmds
    - Remove unnecessary FC_ESTABLISH_LINK logic.
    - Correct some race conditions in the worker thread, resulting in devloss:
      - Clear the work_port_events field before handling the work port events
      - Clear the deferred ring event before handling a deferred ring event
      - Hold the hba lock when waking up the work thread
      - Send an acc for the rscn even when we aren't going to handle it
    - Fix locking behavior that was not properly protecting the ACTIVE flag,
      thus allowing mailbox command order to shift.
