    libvirt: return the correct instance path while cleanup_resize

    If we resized a pre-grizzly instance with grizzly or later nova
    to another host, while the resize confirmation process,
    _cleanup_resize will find the instance resize backup dir and
    delete it, but a wrong xxx_resize dir like ${uuid}_resize,
    instead of the correct ${name}_resize will be found.
    This is because the instance is a resized one which original
    instance dir exists on another host(the dest host),
    get_instance_path method could not find the original instance
    dir on the source host, so the path with uuid will be returned,
    and the `target` existing check in _cleanup_resize is failed,
    then the ${name}_resize dir will never be deleted.
