bgpd: Stop overriding nexthop when BGP unnumberred
When we use vrf-to-vrf export, the nexthop has already not been
overridden when the peer is BGP unnumberred. However, when we use normal
export, the nexthop will be oberridden. This behavior will make the VPN
routes invalid in VPN RIB.
This PR stops overriding nexthop even if we use normal export.
