Subject: [PATCH 2/3] gallium/vl: add chroma_format arg to vl_video_buffer
 functions

vl_mpeg12_decoder needs to override the chroma_format value to get the
correct size calculated (chroma_format is used by vl_video_buffer_adjust_size).

I'm not sure why it's needed, but this is needed to get correct mpeg decode.

Fixes: 24f2b0a8560 ("gallium/video: remove pipe_video_buffer.chroma_format")
