[FFmpeg-devel] ffmpeg_vaapi: fix choice of decoder_format

As discovered and suggested by Mihai Chindea,
http://ffmpeg.org/pipermail/ffmpeg-devel/2016-September/198932.html

I have only inspected/reviewed this change visually, not tested.

The check could previously never evaluate to true, probably due to
a typo.
