[PATCH v2 0/1] MR3955: mf: Avoid a double free of presentation clock timers.

[Zhiyi Zhang (＠zhiyi)]

In clock_change_state() when a clock is running, a timer is removed from clock->timers. The same
timer is then used to create an async result, which will eventually calls present_clock_timer_callback_Invoke()
and removes the same timer.
