Log:
  in6_ifattach_linklocal: handle immediate removal of the new LLA

  If another thread immediately removes the link-local address
  added by in6_update_ifa(), in6ifa_ifpforlinklocal() can return NULL,
  so the following assertion (or dereference) is wrong.
  Remove the assertion, and handle NULL somewhat better than panicking.
  This matches all of the other callers of in6_update_ifa().
