rtnl_register - Register a rtnetlink message type

Identical to __rtnl_register() but panics on failure. This is useful as failure of this function is very unlikely, it can only happen due to lack of memory when allocating the chain to store all message handlers for a protocol. Meant for use in init functions where lack of memory implies no sense in continuing.
