bgpd: VRF-Lite fix to clear stale leaked routes
Description:
Change is intended for fixing the issue related to
clearing of stale leaked routes:
- Whenever BGP goes down,
after bringing down tcp connection and renegotiating capabilities,
once we reestablish connection,
we are not handling clear of VRF leaked route in the bgp_clear_stale_route.
- While bgp is clearing stale routes,
we need to handle withdraw of routes for VRF route-leaking.
