Subject: [PATCH net-next v2 02/13] genetlink: move the private fields in struct genl_family

Move the private fields down to form a "private section".
Use the kdoc "private:" label comment thing to hide them
from the main kdoc comment.

I did this cleanup to add more private fields but ended up
not needing them. Still I think the commit makes sense?
