OpenStack Destroy - retry router interface when subnet in use

[hardys]

This can fail because ports/floating_ips still exist on the subnet
so return such that we retry rather than exit.

The error (reported by @tomassedovic - thanks!) looks like this:

HTTP response code [200] when accessing [PUT http://10.1.8.86:9696/v2.0/routers/baf128bd-850c-4a35-862d-7c9ab87b5673/remove_router_interface], but got 409 instead
{"NeutronError": {"message": "Router interface for subnet e43843c7-64e5-4f8a-a592-b06c998bc73b on router baf128bd-850c-4a35-862d-7c9ab87b5673 cannot be deleted, as it is required by one or more floating IPs.", "type": "RouterInterfaceInUseByFloatingIP", "detail": ""}}
