avcodec/dovi_rpuenc: Avoid intermediate codec par in ff_dovi_configure()

Browse Source 
It invalidates (removes by duplicates)  AVCodecContext.extradata
and AVCodecContext.coded_side_data which is quite surprising
and leads to bugs like #11617 where an AVCPBProperties
is used after it has been freed in ff_dovi_configure().
