queue/queue2: Ensure that the streaming thread is unlocked after deactivating the srcpad

Browse source 
It might happen that the srcpad task function is never called at all, in
which case unlocking everything from there will never happen.

Make sure to unlock everything another time after the task function is
definitely stopped.
