pc-bios/s390-ccw/virtio: Beautify the code for reading virtqueue configuration 

It looks nicer if we separate the run_ccw() from the IPL_assert()
statement, and the error message should talk about "virtio device"
instead of "block device", since this code is nowadays used for
non-block (i.e. network) devices, too.
