scsi: lpfc: Exit PRLI completion handling early if ndlp not in PRLI_ISSUE state
In a large SAN testing configuration, frequent target port toggle tests are
occasionally resulting in missing lun path rediscoveries. An outstanding
PRLI can be inflight when a target RSCN dissappearance occurs, causing the
driver to retry PRLIs using invalid rpi contexts.
Fix by verifying that an ndlp's state was not restarted from PRLI_ISSUE
due to an intermediate RSCN. If not in a valid state, early exit PRLI
completion handling.
The last follow up RSCN indicating target reappearance retriggers
PLOGI/PRLI with a valid rpi context and is expected to succeed in LUN path
rediscovery.
