In addrconf_init we call ipv6_addr_label_init which calls register_pernet_subsys for the ipv6_addr_label_ops structure. But if module loading fails, or if the ipv6 module is removed, there is no corresponding unregister_pernet_subsys call, which leaves a now-bogus address on the pernet_list, leading to oopses in subsequent registrations. This patch cleans up both the failed load path and the unload path. Tested by myself with good results.
