[SCSI] lpfc 8.1.11 : Discovery Fixes 

Discovery Fixes:
 - Prevent starting discovery of a node if discovery is in progress.
 - Code improvement (reduction) for lpfc_findnode_did().
 - Update discovery to send RFF to Fabric on link up
 - Bypass unique WWN checks for fabric addresses
 - Add ndlp to plogi list prior to issuing the plogi els command
