IPv6: only notify protocols if address is compeletely gone
The notifier for address down should only be called if address is completely
gone, not just being marked as tentative on link transistion. The code
in net-next would case bonding/sctp/s390 to see address disappear on link
down, but they would never see it reappear on link up.
