rtnetlink: comment the RCU waits in unregister paths
rtnl_unregister_all() and rtnl_af_unregister() wait for RCU readers
before tearing down what those readers use, but do not say which
readers they are waiting for.
A missing wait is then easy to overlook: rtnl_link_unregister() lacked
its synchronize_rcu() until commit 3b70edea393d ("rtnetlink: wait for
RCU readers in rtnl_link_unregister()"). Add a comment to both waits,
naming the readers each one waits for.
