net: fib_rules: Factorise fib_newrule() and fib_delrule().
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.
