[media] solo6x10: bind start & stop of encoded frames processing thread to device (de)init

Browse Source 
Before, it was called from individual encoder (de)init procedures, which
lead to spare threads running (which were actually lost, leaked).
The current fix uses trivial approach, and the downside is that the
processing thread is working always, even when there's no consumer.
