    Fix privileged create_netns function

    In the patch [1] create_netns function from the Neutron's
    privileged ip_lib module was changed in the way that it was
    implemented in the same way like original pyroute2's create_netns
    function.
    Unfortunately during backporing that patch to stable/ussuri and
    stable/train branches, we probably made mistake and instead of
    calling pyroute2's private function _netns() we still called
    public function netns() (which we tried to "reimplement" really).

    So this patch updates it and changes to use private _netns() function
    from pyroute2, in the same way like it is done in the branches newer
    than stable/ussuri.
