Subject: [PATCH 5.15 092/207] wireguard: allowedips: add missing __rcu annotation to satisfy sparse

From: Jason A. Donenfeld <Jason@...c4.com>

commit ae9287811ba75571cd69505d50ab0e612ace8572 upstream.

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")
