[SCSI] qla2xxx: Revert "qla2xxx: Validate mid-layer 'underflow' during check-conditio...

This reverts commit 8084fe168a5252548cdddf2ed181c337fecd0523.
The midlayer should be given the oppotunity to interpret the
check-condition and based on scsi_cmnd->resid determine if a
transfer should be retried or failed.
