[FFmpeg-cvslog] Fix uninitialized reads for fate-vsynth1-asv2 test.

[Reimar Döffinger]

ffmpeg | branch: master | Reimar Döffinger <Reimar.Doeffinger at gmx.de> | Sun Jan 15 11:01:01 2012 +0100| [8af6b9711e7a9aa80e825aaf901d533d4ff9b7d5] | committer: Reimar Döffinger

Fix uninitialized reads for fate-vsynth1-asv2 test.

This is not a real error and memsetting always even when the
size did not change is overkill, but it still should be
an acceptable trade-off.
