[SCSI] lpfc 8.3.25: Fabric and Target Discovery Fixes 

Fabric and Target Discovery Fixes

- Clear FC_VPORT_NEEDS_INIT_VPI flag during completion of REG_VFI mailbox
  command.
- Prevent SLI3 Code from unregistering the physical VPI.
- Add an else clause to the code that checks and sets
  sp->cmn.request_multiple_Nport to clear the bit.
- Remove a redundant mbox free.
- Modified lpfc_sli4_async_fip_evt to pass in physical VPI toi
  lpfc_find_vport_by_vpid function.
- Modified lpfc_find_vport_by_vpid to translate physical VPI to logical VPI
  before comparing with vport VPI.
