scsi: lpfc: Check devloss callbk done flag for potential stale NDLP ptrs
Should an rport remain in the NOTPRESENT state it is possible that
stgt_delete_work is scheduled after dev_loss_tmo_callbk. In such cases,
dev_loss_tmo_callbk would have cleaned up the NDLP object resulting in
stale ndlp pointers in lpfc_terminate_rport_io().
Check for the DEVLOSS_CALLBK_DONE flag to know if dev_loss_tmo_callbk
has been called. This is a more reliable way to avoid dereferencing
stale NDLP pointers.
