virtio/s390: support READ_STATUS command for virtio-ccw
As virtio-1 introduced the possibility of the device manipulating the status byte, revision 2 of the virtio-ccw transport introduced a means of getting the status byte from the device via READ_STATUS. Let's wire it up for revisions >= 2 and fall back to returning the stored status byte if not supported.
