SG_IO may return additional status in the 'status', 'driver_status',
and 'host_status' fields. When either of these fields are set the
command has not been executed normally, so we should not continue
processing this command but rather return an error.
scsi_read_complete() already checks for these errors,
scsi_write_complete() does not.
