Default gw/dns routes point to drop nh for sub-interface vrf

[amit surana]

Created 512 VLAN sub-interfaces, as children of same parent vmi. It is seen that for some of the VLANs, the route for gw/dns IP points to drop nh. Seen for ~15 vrf/vlans out of 512.

Route notification to ksync missed.

Problem: If VRF notification is not yet
received and route is notified then it does not reach ksync. In absence of ksync
entry for this route, it is not installed in vrouter. Vrf can be notified later
though.

Solution: Ksync will walk routes in vrf whenever vrf ksync entry is
added to look for all missed routes.

Closes-bug: #1661133
