This fixes the problem for me. I tested that SOCK_DESTROY (which uses
inet_diag_find_one_icsk) can successfully find/close the following
AF_INET6 sockets:

- Listen sockets bound to either :: or ::ffff:0.0.0.0
- Accepted IPv4 connections on sockets bound to either :: or ::ffff:0.0.0.0
- Active IPv4 connections
