[FFmpeg-cvslog] swscale: don't omit ff_sws_init_range_convert for high-bit

ffmpeg | branch: master | Niklas Haas <git at haasn.dev> | Sat Oct 28 13:19:52 2023 +0200| [d043e5c54c3f8e98be1a4bc1bcb76407af0e8ac7] | committer: Niklas Haas

swscale: don't omit ff_sws_init_range_convert for high-bit

This was a complete hack seemingly designed to work around a different
bug, which was fixed in the previous commit. As such, there is no more
reason not to do this, as it simply breaks changing color range in
sws_setColorspaceDetails for no reason.
