[SCSI] lpfc 8.3.21: Critical Errors and Bug Fixes

Critical Errors:
- Correctly handle non-zero return lpfc_workq_post_event and return ENOMEM
- Save the irq level when locking the host_lock in lpfc_findnode_did

Bug Fixes:
- Adjust payload_length and request_length for sli4_config mailbox commands.
- Add the freed sgl/XRI to the tail of the list rather than to the head.
- Set the FC_VPORT_NEEDS_INIT_VPI on vport deletes and check it before
  issuing a fdisc on an els retry.
- Only call lpfc_hba_init_link() if phba->cfg_suppress_link_up
  is LPFC_INITIALIZE_LINK.
- Add support for SLI-4 Performance Hints
