62ec07a948 avcodec/vc1dec: Disable error concealment for *IMAGE 
The existing error concealment makes no sense for the image formats, they
use transformed source images which is different from keyframe + MC+difference
for which the error concealment is designed.
Of course feel free to re-enable this if you have a case where it works and
improves vissual results
