    xfrm: Flushing empty SPD generates false events

    To see the effect make sure you have an empty SPD.
    On window1 "ip xfrm mon" and on window2 issue "ip xfrm policy flush"
    You get prompt back in window1 and you see the flush event on window2.
    With this fix, you still get prompt on window1 but no event on window2.
