Zebra: FPM support for gateway IP overlay Index
FPM sends VNI to the data plane with the EVPN prefix. For pure type-5 EVPN
route, nexthop interface of EVPN prefix is L3VNI SVI. Thus, we encode L3VNI
corresponding to the nexthop vrf with rtmsg for this prefix.
For EVPN type-5 route with gateway IP overlay index, we supporting
asymmetric IRB. Thus, nexthop interface is L2VNI SVI. So, instead of fetching
vrf VNI, fetch VNI corresponding to the nexthop SVI and encode it in the rtmsg
for EVPN prefix.
