scsi: lpfc: Introduce FC_RSCN_MEMENTO flag for tracking post RSCN completion

During an NVMe target reboot, the target may initialize itself as FCP only
during the first RSCN and shortly after trigger a second RSCN claiming NVMe
support.  The timing of these RSCNs occur before FCP-PRLI for the first
RSCN completes leading discovery issues over NVMe.

Change RSCN and NVME-PRLI send logic based on a new FC_RSCN_MEMENTO flag
that signals when lpfc_end_rscn() is completed and serves as a memento that
discovery was started from RSCN.
