Removing the deadlock by stopping the fetcher thread before update thread.

I have observed update thread blocked by fetcher thread while going from
PLAYING to PAUSE state. Fetcher thread should be stopped before stopping the
update thread. 

I am attaching a proposed patch for the fix. It works fine for me.
