File 0166-scsi-generic-check-for-additional-S.patch of Package qemu-testsuite.18974

Subject: scsi-generic: check for additional SG_IO status on completion

References: bsc#1178049

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.
