Also check return value of av_frame_copy() in passthrough mode, so that
if a copy fails (as it did here, because bitdepth didn't match), the filter
doesn't return success, which would mean sending an uninitialized framebuffer
further down the filtergraph.

libavfilter/vf_owdenoise.c: skip processing when strength is 0

It is practical to de-noise only on luma while keeping chroma unchanged.
However, libavfilter/vf_owdenoise.c always do the Wavelet transform/retransform on all 3 channels without check whether chroma_strength is 0.
Thus I make this patch. De-noise on Y only for yuv420 is now 1.5 times faster.
