vaapi: turn all mpv users into a living experiment 

Dummy out the locking around all libva calls, which in theory shouldn't
be needed anyway. Two years ago, these were added to prevent crashes
with vaapi decoding and direct rendering (vo_opengl/vo_vaapi) active.

It's not clear whether these are really needed - theory strongly points
towards no. Some developers familiar with vaapi expressed similar
thoughts. But past experience says differently. So let's try
without the locking for a while and see what happens.
