[FFmpeg-cvslog] Remove return statements following infinite loops without break

[Mans Rullgard]

ffmpeg | branch: master | Mans Rullgard <mans at mansr.com> | Sun Jul  3 21:02:18 2011 +0100| [add41decd94b2d3581a3715ba10f27168b8cdb1b] | committer: Mans Rullgard

Remove return statements following infinite loops without break

These statements cannot be reached and are thus not needed.
This removes a number of compiler warnings.
