[SCSI] lpfc 8.2.3 : FC Discovery Fixes
FC Discovery Fixes:
- Fix up lpfc_drop_node() vs lpfc_nlp_not_used() usage
- Clear ADISC flag when unregistering RPI and REMOVE ndlps if in recovery.
- Fix usage of UNUSED list and ndlps
- Fix PLOGI race conditions
- Reset link if NameServer PLOGI errors occur
- Synchronize GID_FT queries with PLOGI receptions
