mlx4_core: Clean up struct mlx4_buf
Now that struct mlx4_buf.u is a struct instead of a union because of the vmap() changes, there's no point in having a struct at all. So move .direct and .page_list directly into struct mlx4_buf and get rid of a bunch of unnecessary ".u"s. Signed-off-by: Roland Dreier <rolandd@cisco.com>
