vo: fix some nonsense

Browse Source 
Commit d38bc531 is incorrect: the 50ms queue-ahead value and the flip
queue offset have different functions. The latter is about calling
flip_page in advance, so the change attempted to show video frames 50ms
in advance on all VOs.

The change was for vo_opengl_cb, but that can be handled differently.
