[NETFILTER]: nf_queue: check if rerouter is present before using it
Every rerouter needs to provide a save and a reroute function, we don't need to check for them. But we do need to check if a rerouter is registered at all for the current family, with bridging for example packets of unregistered families can hit nf_queue.
