Fix implicit logo and RSCN handling for NVMET
NVMET didn't have any RSCN handling at all and
would not execute implicit LOGO when receiving a PLOGI
from an rport that NVMET had in state UNMAPPED.
Clean up the logic in lpfc_nlp_state_cleanup for
initiators (FCP and NVME). NVMET should not respond to
RSCN including allocating new ndlps so this code was
conditionalized when nvmet_support is true. The check
for NLP_RCV_PLOGI in lpfc_setup_disc_node was moved
below the check for nvmet_support to allow the NVMET
to recover initiator nodes correctly. The implicit
logo was introduced with lpfc_rcv_plogi when NVMET gets
a PLOGI on an ndlp in UNMAPPED state. The RSCN handling
was modified to not respond to an RSCN in NVMET. Instead
NVMET sends a GID_FT and determines if an NVMEP_INITIATOR
it has is UNMAPPED but no longer in the zone membership.
