dvdspu: Push update frame, if any, when entering stills.

When entering a still frame generates an updated buffer, make sure
to push it out, otherwise we may not put a frame onscreen with a
rendered button, causing raciness as to whether buttons get drawn
or not when jumping back to the menu on some discs.
