Qos rules not cleaned by L2 agent

[Slawek Kaplonski]

If QoS policy is removed from port when L2 agent is down, then it is not removed after agent is up again. Such qos bandwidth limit rule is still configured on port on L2 agent side (I tested ovs).
How to reproduce:
* Apply QoS policy with bandwidth limit rule to port
* Disable L2 agent
* Remove QoS policy from port
* Start L2 agent
* Bandwidth limit will not be removed from interface in ovs

Changing a qos policy for a port has no problem. But clean is true.

    Clear QoS rules from ports without a qos policy.

    This patch addresses a bug where ports that had their QoS policy
    removed did not have the rules deleted as the agent was restarting
    and cleared the internal port info. This results in the policy still
    being in effect while it has been cleared from the port qos-policy field.
