v4l2: pool: fix assert when mapping video frame with DMA_DRM caps

Browse Source 
Make sure the pool recognizes DMA_DRM caps and parses them into
GstVideoInfo that has GstVideoFormat corresponding to "drm-format"
in the caps.

Fixes
  gst_video_frame_map_id: assertion 'info->finfo->format ==
meta->format' failed

Where the left side of the assertion was GST_VIDEO_FORMAT_DMA_DRM and
the right side was some GstVideoFormat converted from DRM fourcc.
