scsi: lpfc: Clear NLP_IN_DEV_LOSS flag if already in rediscovery

Browse Source 
In dev_loss_tmo callback routine, we early return if the ndlp is in a state
of rediscovery.  This occurs when a target proactively PLOGIs or PRLIs
after an RSCN before the dev_loss_tmo callback routine is scheduled to run.
Move clear of the NLP_IN_DEV_LOSS flag before the ndlp state check in such
cases.
