scsi: lpfc: Driver fails to detect direct attach storage array 

The driver does not respond to PLOGI from the direct attach target.  The
driver uses incorrect S_ID in CONFIG_LINK, after FLOGI completion

Correct by issuing CONFIG_LINK with the correct S_ID after receiving the
PLOGI from the target
