MSDK recognizes both yuv420p10 and yuv420p9 as MFX_FOURCC_P010, but parameters are different. When decode yuv420p9 video, ffmpeg-qsv will use yuv420p10le to configure surface which is different with param from DecoderHeader and this will lead to error. Now change it use param from decoderHeader to configure surface.
