If an API user only has access to the ci FSM (which is managed via an opaque struct), provide this function to obtain the backpointer to the parent endpoint FSM, mostly to be able to call osmo_mgcpc_ep_cancel_notify() on it. osmo-msc's rtp_stream FSM will use this in I351bb8e8fbc46eb629bcd599f6453e2c84c15015.
