bgpd: fix evpn mh esi flap remove local routes
In symmetric routing, when local ESI is down,
the MH peer learnt local mac-ip
prefix is installed into teannt vrf (given l3vni).
When ESI is back up and associated to evi/vni then
remove the local synced mac-ip imported routes from the
tenant vrf as local neigh/arp is present.
Ticket: #3878699
Testing:
peer advertised mac-ip route:
*> [2]:[0]:[48]:[aa:aa:aa:00:00:01]:[32]:[45.0.0.51] RD 27.0.0.4:9
27.0.0.4 (spine-1)

When local ESI is flapped
torm-11:# ip neigh show 45.0.0.51
45.0.0.51 dev vlan1000 lladdr aa:aa:aa:00:00:01 REACHABLE proto zebra
Before fix:
(The imported route remained in tenant-vrf)
torm-11:# ip route show vrf vrf1 45.0.0.51
45.0.0.51 nhid 257 proto bgp metric 20
After fix:
torm-11# ip route show vrf vrf1 45.0.0.51
