[PATCH 6/7] lpfc 8.1.5 : Misc small fixes

[James Smart]

Contains the following misc fixes:
 - Fix build warnings
 - Race condition in lpfc_workq_post_event() could corrupt phba->work_list.
 - nlp_sid was not being initialized properly
 - Fix some RSCN handling during the re-discovery after Link Up event.
