ipv6: add a missing unregister_pernet_subsys call
Clean up a missing exit path in the ipv6 module init routines. 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.
