[SCSI] lpfc 8.3.10: Fix Discovery issues

- Prevent Vport discovery after reg_new_vport completes when physical
  logged in using FDISC.
- Remove fast FCF failover fabric name matching. Allow failover to FCFs
  connected to different fabrics.
- Added fast FCF failover in response to FCF DEAD event on current
  FCF record.
