[FFmpeg-cvslog] Fix build with threading disabled

[Mans Rullgard]

ffmpeg | branch: master | Mans Rullgard <mans at mansr.com> | Wed Feb  9 20:15:25 2011 +0000| [ee5bb31f9953d356c5caa08bd16451d017780759] | committer: Michael Niedermayer

Fix build with threading disabled

The avcodec_thread_free() compatibility wrapper calls ff_thread_free(),
which is not defined when threading is disabled.  Make this call
conditional.
