scsi: lpfc: Correct MDS diag and nvmet configuration
A recent change added some MDS processing in the lpfc_drain_txq routine
that relies on the fcp_wq being allocated. For nvmet operation the fcp_wq
is not allocated because it can only be an nvme-target. When the original
MDS support was added LS_MDS_LOOPBACK was defined wrong, (0x16) it should
have been 0x10 (decimal value used for hex setting). This incorrect value
allowed MDS_LOOPBACK to be set simultaneously with LS_NPIV_FAB_SUPPORTED,
causing the driver to crash when it accesses the non-existent fcp_wq.
Correct the bad value setting for LS_MDS_LOOPBACK.
Fixes: ae9e28f36a6c ("lpfc: Add MDS Diagnostic support.")
