    Fix updating device names when defaulting

    If the virt driver does not support defaulting device names, the default
    behaviour of defaulting them in the manager was calling the conductor
    block_device_mapping_update method with the wrong arguments, which
    caused a TypeError and ultimately a failure to boot the instance.

    This patch fixed the signature and adds a test that exercises it so
    that it does not regress.
