I'm not sure this is a neutron issue, as you are allowed to delete a port even if it is in use.
It seems like the issue is with Nova, but before re-assigning, have you tried removing the port via the CLI?
# openstack server remove port <server> <port>
That will probably do the right thing. There is also an 'add port'.
