ovs-agent exception non-existent ports

[Aaron Rosen]

If a HV is rebooted the tap interfaces connected to br-int are not persistent after rebooted. Then when ovs_quantum_agent starts it issues an "ovs-vsctl list-ports br-int" in order to determine the interfaces attached to br-int. Then, it tries to configure them which causes the following exception:

Traceback (most recent call last):

I do not believe this is directly related to: https://bugs.launchpad.net/quantum/+bug/1009215 though the reason for that bug could be along the same lines as this one.
