vo_xv: don't call vo_xv_get_eq() on every frame

Browse Source 
This was done to query the colorspace for sub/OSD rendering. A
single vo_xv_get_eq() call probably requires a dozens of round-trips
(depending what xlib actually does). This likely wasn't a real problem,
but it might be better to be paranoid about this.
