genetlink: add small version of ops
We want to add maxattr and policy back to genl_ops, to enable
dumping per command policy to user space. This, however, would
cause bloat for all the families with global policies. Introduce
smaller version of ops (half the size of genl_ops). Translate
these smaller ops into a full blown struct before use in the
core.
v1:
- use struct assignment
- put a full copy of the op in struct genl_dumpit_info
- s/light/small/
