The only down side, is that userspace will not be aware that the encoder could not store the colorimetry into the bitstream. What I totally agree, is that this should not prevent encoding the stream, but the stream should also not lie about it (which this change fixes).

record the colorspace set by user. if it's not supported by h264 vui, then zero will be written to vui, but don't modify the user setting.
