vf_colorspace: don't enable passthrough if bitdepth doesn't match.

Browse Source 
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.
