[FFmpeg-cvslog] avcodec/pthread_frame: Properly unref frame in case of decoding failure

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Sun Feb  6 15:18:09 2022 +0100| [e1edfe641609b08288090b77dc439861f75df5ea] | committer: Andreas Rheinhardt

avcodec/pthread_frame: Properly unref frame in case of decoding failure

Use ff_thread_release_buffer() instead of av_frame_unref(),
as the former handles the case of non-thread-safe callbacks
properly. (This is possible now that ff_thread_release_buffer()
no longer requires a ThreadFrame.)
