(cherry picked from commit 8595805aafc8b077e01804c9a3668e9aa3510e89)

The notifier for address down should only be called if address is completely
gone, not just being marked as tentative on link transition. 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.
