    Fix device_create method in ovsvapp_agent

    We shouldn't update the devices_to_filter for port id's belonging to VM's
    hosted on other ESX hosts.

    In the scalability setup we have observed that due to unavailability of
    resources on a given ESX nova delete the VM's and neutron eventually deletes
    the port associated to that VM from DB, since OVSvApp agent running on other
    ESX host tries to delete the flows for that port it won't be able to find in
    neutron DB and get_ports_details_list RPC throws exception and stuck in loop.
