Revert "ipv6: Revert optional address flusing on ifdown."

This reverts commit 841645b5f2. Ok, this puts the feature back. I've decided to apply David A.'s bug fix and run with that rather than make everyone wait another whole release for this feature. Signed-off-by: David S. Miller <davem@davemloft.net>
