Eric Dumazet 9f30831390 net: add rcu safety to rtnl_prop_list_size()
rtnl_prop_list_size() can be called while alternative names
are added or removed concurrently.

if_nlmsg_size() / rtnl_calcit() can indeed be called
without RTNL held.

Use explicit RCU protection to avoid UAF.

Fixes: 88f4fb0c74 ("net: rtnetlink: put alternative names to getlink message")
