Called by the timebase master to release itself from that
responsibility.
If the timebase master releases the timebase or leaves the JACK
graph for any reason, the JACK engine takes over at the start of
the next process cycle. The transport state does not change. If
rolling, it continues to play, with frame numbers as the only
available position information.

@param client the JACK client structure.
@return 0 on success, otherwise a non-zero error code.
