Subject: vf_vapoursynth: fix obscure/impossible leak

Unknown frames were not freed properly. Although this doesn't really
happen anyway, because we're never going to feed audio frames to a video
filter chain. Since it's theoretically possible, and all other filters
handle this consistently, fix it anyway.
