[FFmpeg-cvslog] avcodec/vc2enc: Fix slice length

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Sat May 25 20:32:42 2024 +0200| [02ecf8d7f3fe6ad6bc493a37bfff65bfe9150113] | committer: Andreas Rheinhardt

avcodec/vc2enc: Fix slice length

args->bytes here already includes prefix_bytes (see
SSIZE_ROUND macro), so including it here again and
forgetting it when offsetting skip seems wrong.
This only works because prefix_bytes is currently
always zero in this encoder.
(This has been added in b88be742fac7a77a8095e8155ba8790db4b77568
without any reason.)
