    RBD: Don't flatten temporary resources

    There are instances where cinder needs to create a temporary volume and
    this can trigger a flatten of the new temporary volume, which will make
    the operation take a lot longer.

    In some cases this means slower operations, but in others it leads to
    rpc timeout failures.

    A case where we see timeout failures is when doing a backup of a
    snapshot and we have rbd_flatten_volume_from_snapshot=true.

    This patch ensures that we don't flatten temporary volumes.
