scsi: lpfc: Fix NULL ptr dereference with NPIV ports for RDF handling

Browse source

RDF ELS handling for NPIV ports may result in an incorrect NDLP reference
count.  In the event of a persistent link down, this may lead to premature
release of an NDLP structure and subsequent NULL ptr dereference panic.

Remove extraneous lpfc_nlp_put() call in NPIV port RDF processing.
