zebra: Push all configured IP addresses when the interface comes up

Let's say we this: ``` $ ip link set down dev r1-eth0 $ ip link set up dev r1-eth0 ``` But at the same time we have this interface configured by the FRR too: ``` interface r1-eth0 ipv6 address fe80:1::1/64 exit ``` We never re-add fe80:1::1/64, when the interface comes up, and we have a strange situation where NHT stops working and other stuff depending on NHT stops too (BGP peering, etc.).
