…w EVPN triggers
In cases such as 'no advertise-all-vni' and L2 VNI DELETE, we need to
pop all the VPN routes present in the bgp_zebra_announce FIFO yet to
be processed regardless of VNI is configured or not.
NOTE: NO need to pop the VPN routes in two cases
1) In free_vni_entry
- Called by bgp_free()->bgp_evpn_cleanup().
- Since bgp_delete is called before bgp_free and we pop all the dest
pertaining to bgp under delete.
2) evpn_delete_vni() when user configures "no vni" since the withdraw
of all routes happen in normal cycle.
