    Do not fail when depth is greater than rbd_max_clone_depth

    Removed a sanity check in the code that raised an exception
    if the clone depth of a volume to be cloned exceeded the
    rbd_max_clone_depth config value. A consequence of this
    check was that if an operator lowered the value, volumes
    whose clone depth was greater than the new value (as would
    be allowed by the previous, higher setting) could no longer
    be cloned.
