Subject: [PATCH v2 net-next 03/11] neighbour: Use rtnl_register_many().
We will remove rtnl_register() in favour of rtnl_register_many().
When it succeeds, rtnl_register_many() guarantees all rtnetlink types
in the passed array are supported, and there is no chance that a part
of message types is not supported.
Let's use rtnl_register_many() instead.

v2:
* Add __initconst
* Use C99 initialisation
