fib_nl_newrule() / fib_nl_delrule() is the doit() handler for RTM_NEWRULE / RTM_DELRULE but also called from vrf_newlink(). Currently, we hold RTNL on both paths but will not on the former. Also, we set dev_net(dev)->rtnl to skb->sk in vrf_fib_rule() because fib_nl_newrule() / fib_nl_delrule() fetch net as sock_net(skb->sk). Let's Factorise the two functions and pass net and rtnl_held flag.
