libsas: fix NCQ mixing with non-NCQ
commit f0ad30d3d2dc924decc0e10b1ff6dc32525a5d99 upstream.
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
