dcb: 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.
