    net: rtnetlink: ignore NETDEV_PRE_UP notifier in rtnetlink_event()
    
    Commit 3b8bcfd (net: introduce pre-up netdev notifier) added a new
    notifier which is run before a device is set UP for use by cfg80211.
    
    The patch missed to add the new notifier to the ignore list in
    rtnetlink_event(), so we currently get an unnecessary netlink
    notification before a device is set UP.
