zebra: send interface updates when down
When interfaces change while they are up, Zebra sends if_up
notifications with the updated interface info. Change Zebra to send
if_down notifications with interface info when the interface changes
while it is down.
VRRP, at the least, needs these to know about MAC changes while an
interface is down.
