[SCSI] lpfc 8.3.21: FC Discovery changes
FC Discovery changes - Treat received PLOGI while logged in as a relogin (unregister and reregister). - Added a timer to delay Nport discovery when clean bit is cleared and Fabric portname/nodename/FCID is changed. - Invalidate Port's DID when receiving PLOGI from p2p port with CONFIG_PORT mailbox command.
