ovsfw doesn't support cidr in allowed_address_pairs

[Inessa Vasilevskaya]

Seen on: ocata devstack

Steps to reproduce:

1. update port with allowed_address_pairs as cidr, for example

 neutron port-update 2559e0ff-6a52-4b78-9471-246fecb846c0 --allowed-address-pairs type=dict list=true ip_address=192.168.0.0/30

2. switch to openvswitch firewall
firewall_driver=openvswitch in /etc/neutron/plugins/ml2/ml2_conf.ini

3. observe a bunch of errors in openvswitch-agent log (http://paste.openstack.org/show/600933/)

with ValueError: IPAddress() does not support netmasks or subnet prefixes! See documentation for details.
