    Do not rename rbd based volume after migration

    After rbd based volume migrated (retyped), it will be
    renamed to the original name unless name collision or
    some errors happen. But the problem is this information
    seems not reflect on connection info, especially this volume
    is already in-use.

    This patch mimics behavior of lvm driver by not renaming
    in-used volume after migration(retype)
