Subject: [PATCH net 01/10] wireguard: allowedips: add missing __rcu annotation to satisfy sparse

A __rcu annotation got lost during refactoring, which caused sparse to
become enraged.

Fixes: bf7b042dc62a ("wireguard: allowedips: free empty intermediate nodes when removing single node")
Cc: stable@...r.kernel.org
