[SCSI] libsas: fix NCQ mixing with non-NCQ
Some cards (like mvsas) have issue troubles if non-NCQ commands are mixed with NCQ ones. Fix this by using the libata default NCQ check routine which waits until all NCQ commands are complete before issuing a non-NCQ one. The impact to cards (like aic94xx) which don't need this logic should be minimal Cc: Stable Tree <stable@kernel.org> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
