Subject: [PATCH] addons: vxlan: fix compare between remote-ips and
 old_remote_ips

fix regression from
https://github.com/CumulusNetworks/ifupdown2/commit/35a4278ffb588ddd9e610f9395853ff35923c069

remote-ips can be None (with evpn for example) but old_remote_ips is an empty list.
So the condition is always matching
