    [OVN] Prevent Trunk creation/deletion with parent port bound

    This patch imitates the ML2/OVS Trunk driver behaviour. When the
    trunk parent port is bound:
    * A new trunk cannot be created using this parent port.
    * If the port is assigned as parent port of a trunk, this
      trunk cannot be deleted.
