cooker: Ensure parse_quit thread is closed down

Each run through the parser would leak a thread from the queue created to
shut the parser down. Close this down correctly and clean up the code flow
slightly whilst in the area, making sure this thread does shut down correctly
(we don't care if it loses data).
