[FFmpeg-cvslog] lavf: fix memleaks in avformat_find_stream_info()

[Justin Ruggles]

ffmpeg | branch: master | Justin Ruggles <justin.ruggles at gmail.com> | Mon Sep 16 15:51:46 2013 -0400| [19133e96d30e3f80dbae236ef081aedef419a6bf] | committer: Anton Khirnov

lavf: fix memleaks in avformat_find_stream_info()

When AVFMT_FLAG_NOBUFFER is set, the packets are not added to the
AVFormatContext packet list, so they need to be freed when they are
no longer needed.
