scsi: lpfc: Qualify ndlp discovery state when processing RSCN

Conditionalize when to put an ndlp into recovery mode when processing
RSCNs.  As long as an ndlp state is beyond a PLOGI issue and has been
mapped to a transport layer before, the ndlp qualifies to be put into
recovery mode.  Otherwise, treat the ndlp rport normally through the
discovery engine.
