[Multimedia] Fixed a deadlock issue of Player.SetPlayPositionAsync.

It occurs when the continuation of task is syncrhonous, which is not always.

The callback in native holds a mutex, if user code tries to call SetPlayPositionAsync right after awaiting SetPlayPositionAsync. It could be blocked, the mutex is still locked.
