vo_opengl: don't discard buffered video on redundant resize calls

Browse Source 
If a VO-area option changes, gl_video_resize() is called
unconditionally. This function does something even if the size does not
change (at least it discards buffered frames for interpolation), which
can lead to stutter when you keep firing option change events during
playback.

Check for an actual resize, and if nothing changes, exit early.
