[SCSI] lpfc 8.3.5: fix reset path, ELS ordering and discovery issues
This patch includes the following fixes:
- Fixed panic during HBA reset.
- Fixed FCoE event tag passed in resume_rpi.
- Fix out of order ELS commands
- Fixed discovery issues found during VLAN testing.
- Fix UNREG_VPI failure on extended link pull
- Fixed crash while processing unsolicited FC frames.
- Clear retry count in the delayed ELS handler
- Fixed discovery failure during quick link bounce.
