neutron: don't trace on port not found when unbinding ports
There is a race in the gate when deleting an instance and
deallocating the network at the same time that preexisting
ports attached to the instance are being deleted. So when
nova goes to unbind the port it's already gone and we log
an exception trace in the n-cpu logs. We shouldn't actually
care if the port isn't found when unbinding it from an instance,
so this change handles that case and logs it at debug rather
than an exception trace.

Title:
PortNotFoundClient stacktrace in n-cpu when unbinding ports
Status in OpenStack Compute (nova):
Fix Released
Bug description:
Saw this in a CI run today:
http://logs.openstack.org/07/367307/1/check/gate-tempest-dsvm-neutron-
full-ubuntu-
xenial/cf54759/logs/screen-n-cpu.txt.gz?level=TRACE#_2016-09-08_12_05_26_139
We shouldn't stacktrace on a 404 port not found when unbinding ports
from an instance (that is probably be deleted).
