[FFmpeg-cvslog] exr: fix header parsing

[Jean First]

ffmpeg | branch: master | Jean First <jeanfirst at gmail.com> | Tue May 15 16:34:58 2012 +0200| [f7985f348f1eb3ec6a1670bc1accfe2c80b55148] | committer: Michael Niedermayer

exr: fix header parsing

the header in the sample provided for ticket #1306 is not parsed correctly and thus
ffmpeg tries to decode the sample instead of abording the decoding.

I tested it with two other exr samples I have - one float, one half float - and
they still decode correctly.
