[SCSI] qla2xxx: Additional residual-count corrections during UNDERRUN handling.

Add additional tightening of residual-count handling (originally
from commit 6acf8190025e9c4ea513d4084ff089d476112816) where the
driver should discard any lower SCSI-status during
firmware/transport residual-count mismatches.
