[IPV6]: Fix rtnetlink dump infinite loop
The recent change to netlink dump "done" callback handling broke IPv6 which played dirty tricks with the "done" callback. This causes an infinite loop during a dump. The following patch fixes it. This bug was reported by Jeff Garzik. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
