memcg, kmem: fix build error when CONFIG_INET is disabled

Commit e1aab161 ("socket: initial cgroup code.") causes a build
error when CONFIG_INET is disabled in Linus' tree:

  net/built-in.o: In function `sk_update_clone':
  net/core/sock.c:1336: undefined reference to `sock_update_memcg'

sock_update_memcg() is only defined when CONFIG_INET is enabled, so fix
it by defining the dummy function without this option.
