sthal: close active tunneling during stop recognition

note: The application layer abnormal behavior will stop active
      tunneling streaming. That will cause codec problem.
      So we close active tunneling when the application try to stop
      the recognition.

Test: verify the ambient fetching data and on/off stress.
