    Use disk_bus when guessing the device name for vol

    Even though the disk bus could be set through hw_disk_bus property,
    the libvirt driver didn't guess the proper bus and device name for the
    root volume and expected it to be defined in the BDM.

    With this patch, we consider the predefined disk_bus when going to guess
    the volume device name and bus instead of just relying on the one
    defined in the BDM.
