[PATCH] qcap: Fix always wait for ReadThread to end when fiter_Stop.

[Jiajin Cui]

There is a very small probability that the ReadThread will always wait for run_event signal after filet_Stop calls qcap_driver_stop_stream, and then filter_Stop is stuck waiting for the ReadThread to exit when calling qcap_driver_cleanup_stream. This issue was found in the video call hang up of Tencent QQ application.
