Eric Dumazet ac0841d7d2 net: prevent possible UAF in rtnl_prop_list_size() 
I was mistaken by synchronize_rcu() [1] call in netdev_name_node_alt_destroy(),
giving a false sense of RCU safety at delete times.

We have to use list_del_rcu() to not confuse potential readers
in rtnl_prop_list_size().

[1] This synchronize_rcu() call was later removed in commit 723de3ebef
("net: free altname using an RCU callback").

Fixes: 9f30831390 ("net: add rcu safety to rtnl_prop_list_size()")
