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