    Adding code to prevent vip port deletion from port api

    When a lbaas port is deleted from the port delete command from
    neutron it tries to delete the port but since it is being held
    for the vip the database update fails and neutron throws a 500
    error

    This fix checks if the vip is associated to the port and allows
    deletion of the port only if there is no vip associated with the
    port
