[FFmpeg-devel] [PATCHv2] avcodec/videotoolbox: fix -Wunused-but-set-variable

[Ganesh Ajjanagadde]

pix_fmt was declared presumably to shorten the argument passed to the function.
However, it is currently not being used for such a purpose.
This patch simply removes it instead.
This fixes -Wunused-but-set-variable reported at e.g:
http://fate.ffmpeg.org/log.cgi?time=20150919194249&log=compile&slot=x86_64-darwin-gcc-4.9.
