floating_ip_disassociate port_id parameter never used

[LIU Yulong]

Code:

Neutron:

openstack_dashboard/api/neutron.py

    def disassociate(self, floating_ip_id, port_id):
        update_dict = {'port_id': None}
        self.client.update_floatingip(floating_ip_id,
                                      {'floatingip': update_dict})

Nova:

openstack_dashboard/api/nova.py

    def disassociate(self, floating_ip_id, port_id):
        fip = self.client.floating_ips.get(floating_ip_id)
        server = self.client.servers.get(fip.instance_id)
        self.client.servers.remove_floating_ip(server.id, fip.ip)

python-neutronclient usage:
neutron floatingip-disassociate [-h] [--request-format {json,xml}] FLOATINGIP_ID

python-novaclient usage:
nova floating-ip-disassociate <server> <address>
