    GlusterFS: Fix deadlock in volume clone

    The create_cloned_volume path could deadlock due to
    create_cloned_volume and create/delete_snapshot using the same
    lock for synchronization.

    Refactor the calls to create/delete snapshot to call the inner
    method which does not use a lock.
