    Fix extra metadata didn't assign into snapshot image

    create_image action API accept metadata parameter to add extra
    metadata into snapshot image. But the current code doesn't work
    for snapshot of volume based instance. This error is because the
    code use var 'props' to store extra metadatas, and the code use
    same var to store root bdm metadata later, then the extra metadata
    is overwritten by root bdm metadata. This patch use another var
    'properties' to store root bdm metadata to avoid overwrite the
    extra metadata.
