ffmpeg | branch: release/2.7 | Gwenole Beauchesne <gwenole.beauchesne at intel.com> | Tue Jun 23 11:35:45 2015 +0200| [071d7f4e179a18a403063c57f92664e8079def09] | committer: Gwenole Beauchesne

vaapi_h264: fix RefPicList[] field flags.

Use new H264Ref.reference field to track field picture flags. The
H264Picture.reference flag in DPB is now irrelevant here.

This is a regression from git commit d8151a7, and that affected
multiple interlaced video streams.
