msdk: return the right pointer

Browse source 
The first channel in memory for MFX_FOURCC_RGB4 (VA_FOURCC_ARGB or
GST_VIDEO_FORMAT_BGRA) is B, not A. In MSDK, channle B is used to access
data for RGB4 surface. In addition, the returned pointers for
MFX_FOURCC_AYUV and MFX_FOURCC_Y410 in gst_msdk_video_memory_map_full
were wrong too before this fix.
