genetlink: reorg struct genl_family
There are holes and oversized members in struct genl_family.
Before: /* size: 104, cachelines: 2, members: 16 */
After: /* size: 88, cachelines: 2, members: 16 */
The command field in struct genlmsghdr is a u8, so no point
in the operation count being 32 bit. Also operation 0 is
usually undefined, so we only need 255 entries.
netnsok and parallel_ops are only ever initialized to true.
We can grow the fields as needed, compiler should warn us
if someone tries to assign larger constants.
