[Libva] [PATCH 2/2] mpeg2: check frame_pred_frame_dct instead of progressive_frame

[Xiang, Haihao]

From: "Xiang, Haihao" <haihao.xiang at intel.com>

Some MPEG-2 videos set progressive_frame to 1 and set
frame_pred_frame_dct to 0, which is not conformed to MPEG-2 spec.
bottom field may be used to form prediction if frame_pred_frame_dct is
0. Previously the bottom field is excluded from the frame store list
