decklink-output-ui: Fix crash when stopping preview 

Removing the first call to `video_output_stop` prevents the `data_mutex`
field in `struct video_output` from being destroyed while still in use.
The `render_preview_source` function will call `video_output_lock_frame`
upon that mutex and encounter a NULL pointer exception.
