scsi: lpfc: Account for fabric domain ctlr device loss recovery

Browse Source 
Pre-existing device loss recovery logic via the NLP_IN_RECOV_POST_DEV_LOSS
flag only handled Fabric Port Login, Fabric Controller, Management, and
Name Server addresses.

Fabric domain controllers fall under the same category for usage of the
NLP_IN_RECOV_POST_DEV_LOSS flag.  Add a default case statement to mark an
ndlp for device loss recovery.
