'IPDB' object has no attribute 'interface' in utils.remove_device

[Liping Mao]

IPDB only have 'interfaces' attribute, we miss spelling it to 'interface' in utils.remove_device, this will cause it failed when call function "remove_device" in utils.py

Here is a sample:

vagrant@devstack:/opt/stack/kuryr/kuryr/lib/binding/drivers$ docker run -it --net=test1 busybox
docker: Error response from daemon: NetworkDriver.Join: 'IPDB' object has no attribute 'interface'.
