Since commit a388f78c8c, we fetch
routers' existing floating ip address from the fip namespace's
route table instead of qrouter namespace's qg device for the
dvr_local and dvr_edge router. But for dvr_edge_ha router, it
still fetch the existing floating ip like legacy router, causing
it can’t know which existent floating ip rules need to be removed.
After removing the get_router_cidrs method, the dvr_edge_ha router
inherit the get_router_cidrs method from dvr_local router and it
will remove the existent floating ip rules successfully if we
disassociate the floating ip.
