[FFmpeg-cvslog] Replace assert with AVERROR when recode_subtitle called w/o ICONV.

[Dale Curtis]

ffmpeg | branch: master | Dale Curtis <dalecurtis at chromium.org> | Tue May 20 12:03:57 2014 -0700| [ef0c466a0fef4657d3f46cc9adea97e76a8e4faa] | committer: Michael Niedermayer

Replace assert with AVERROR when recode_subtitle called w/o ICONV.

recode_subtitle() is called implicitly by avformat_find_stream_info().
As such, clients which disable ICONV always crash if a file contains
subtitles; even if they don't care about them.
