    ipvs: fix oops in ip_vs_dst_event on rmmod
        After commit 39f618b4fd95ae243d940ec64c961009c74e3333 (3.4)
    "ipvs: reset ipvs pointer in netns" we can oops in
    ip_vs_dst_event on rmmod ip_vs because ip_vs_control_cleanup
    is called after the ipvs_core_ops subsys is unregistered and
    net->ipvs is NULL. Fix it by exiting early from ip_vs_dst_event
    if ipvs is NULL. It is safe because all services and dests
    for the net are already freed.
