ipmr: Use rtnl_register_many().
We will remove rtnl_register() and rtnl_register_module() in favour
of rtnl_register_many().
When it succeeds for built-in callers, 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.
