[FFmpeg-cvslog] AVOptions: remove AVOption.offset <= 0 checks

[Anton Khirnov]

ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Mon Sep  5 21:44:33 2011 +0200| [4dbcdfa86d1405f7e5c0ec14a4be7d2fb5903d7b] | committer: Anton Khirnov

AVOptions: remove AVOption.offset <= 0 checks

They will only ever be <=0 if the option is broken, in which case this
check is hiding a bug.
