[FFmpeg-cvslog] cmdutils: use sws_freeContext() instead of av_freep().

[Ronald S. Bultje]

ffmpeg | branch: master | Ronald S. Bultje <rsbultje at gmail.com> | Fri May 27 11:57:39 2011 -0400| [faf8d3ddfa105d7f107a886c5f3cadf6357d89b6] | committer: Ronald S. Bultje

cmdutils: use sws_freeContext() instead of av_freep().

av_freep(swsContext) will leak all memory potentially
allocated within the swsContext.
