ffmpeg | branch: master | Timo Rothenpieler <timo at rothenpieler.org> | Sun Nov 12 15:15:55 2017 +0100| [3e0e1634585b1a26b7d753aa42c7f350636927ae] | committer: Timo Rothenpieler

avcodec/nvdec: don't add thread buffer twice

This is already added to the initial pool size in ff_decode_get_hw_frames_ctx,
so adding it here again increases the amount of surfaces needlessly.
