Public bug reported:

When an update for a dhcp port fails, a keyerror on missing network_id
while attempting to log a trace masks the underlying exception. An
example is here:

http://logs.openstack.org/91/94891/1/check/check-tempest-dsvm-
neutron/c87b4fc/logs/screen-q-svc.txt.gz?level=TRACE

This is because on update, the dhcp agent only sends either this:

https://github.com/openstack/neutron/blob/master/neutron/agent/linux/dhcp.py#L770

or this:

https://github.com/openstack/neutron/blob/master/neutron/agent/linux/dhcp.py#L787

Port uuid is always there, so we might be better off using it instead.
