[SCSI] lpfc 8.3.8: BugFixes: SLI relates changes

Browse Source 
Fix hardware/SLI relates issues:
- Handle XB bit so that ELS XRIs are not prematurely released.
- Handle XB bit so that FCP XRIs are not prematurely released.
- Define new security SLI Commands.
- Remove unused security SLI commands
- Skip receive data size parameter check on received FLOGI.
- Added LPFC_USE_FCPWQIDX flag to iocb to force SLI layer
  to submit abort WQE on same WQ as the command WQE.
