net: fix two lockdep splats

Commit e67f88dd12f6 (net: dont hold rtnl mutex during netlink dump
callbacks) switched rtnl protection to RCU, but we forgot to adjust two
rcu_dereference() lockdep annotations :

inet_get_link_af_size() or inet_fill_link_af() might be called with
rcu_read_lock or rtnl held, so use rcu_dereference_rtnl()
instead of rtnl_dereference()
