net: hold rtnl again in dump callbacks
Commit e67f88dd12f6 (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.
