Add a check in the device post processing for any disk using iothread to be
using the proper bus (which happens to be only virtio for now).
This check could have been added in device parse, except that if a domain
was running with such a configuration (albeit doing nothing), then it
would disappear. Found while working through code to add iothreads for
virtio-scsi-{pci,ccw}.
