    Fix root_device_name for Xen

    When running the Tempest scenario test_volume_boot_pattern.\
         TestVolumeBootPattern.test_volume_boot_pattern with a
    libvirt+Xen environment, the tests fails because the
    root_device_name is set to 'vda' which is invalid for Xen.
    When getting the BDM for the root block device, check that
    the root_device_name is compatible with the used disk bus and
    if it is not, adjust the root_device_name.
