scsi: lpfc: Rework FDMI initialization after link up
After a link up, it's possible for the switch to change FDMI support (e.g.
FDMI1 vs FDMI2 vs SmartSAN). If the switch reverts to FDMI1, then the
revert is currently not detected.
Additionally, when NPIV is configured, it's possible the physical port's
RHBA is unprocessed by the switch before reciept of an NPIV port issued
RPRT. This causes some switches vendors to reject the NPIV's RPRT.
Fix by reinitializing base FDMI mode on link up, and defer FDMI vport RPRT
submission until after confirming physical port's RHBA is completed.
