net: hold rtnl again in dump callbacks
Commit e67f88dd (dont hold rtnl mutex during netlink dump callbacks) missed fact that rtnl_fill_ifinfo() must be called with rtnl held. Because of possible deadlocks between two mutexes (cb_mutex and rtnl), its not easy to solve this problem, so revert this part of the patch. It also forgot one rcu_read_unlock() in FIB dump_rules() Add one ASSERT_RTNL() in rtnl_fill_ifinfo() to remind us the rule.
