Public bug reported:

For openvswitch security group, due to some extreme case, if ofport is
processed once, the openvswitch     security driver will cache some old
ofport informations with different local vlan from current assignment.
Then wrong flow installed.

Should always get local_vlan tag from the OVSDB Port other_config, since
ovs-agent's local_vlan_manager allocated/updated it before security
group flows processing.
