    Remove port resource change after unplug
    
    Ports are removed (unplug) from the br-int, but
    the ovs-agent resource_cache still have them.
    If during this removal period, the port attributes
    changed/updated. Even worse if the update events
    were not received by the agent, as well as the
    port plug to the br-int again. The ovs-agent will
    use the obsolete resource informaction of the port.
    Something may not be processed well then.
    
    So, resource cache should be delete after port removed
    from br-int. This patch addresses this issue.
