    Fix implicit logo and RSCN handling for NVMET · 1c5b12f7
    James Smart authored
    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.
