Bug description:
As part of the instance deletion process, we must unbind ports
associated with said instance. To do this, we loop over all ports
currently attached to an instance. However, if neutron returns HTTP
404 (Not Found) for any of these ports, we will return early and fail
to unbind the remaining ports. We've seen the problem in the context
of Kubernetes on OpenStack. Our deinstaller is brute-force, so it
deletes ports and servers at the same time, so a race means the port
can get deleted early. This normally wouldn't be an issue as we'd just
"untrunk" it and proceed to delete it. But that won't work for SR-IOV
ports as in that case you cannot "untrunk" bound ports.
The solution here is obvious: if we fail to find a port, we should
simply skip that and continue unbinding everything else.
