Hmm... The idea was to make sure that scan is canceled before
cfg80211_netdev_notifier_call throws WARN when state is changed
to NETDEV_DOWN. However this is not needed if scans are properly
canceled in cfg80211_ops handlers. Thanks for catching, will remove.

That was minor optimization: to remove pedning timer whenever scan
is canceled. Sure, it worth mentioning in changelog, will do.
By the way, is it ok to send corrected single patch in reply to this
discussion ? Or the appropriate way is to resend the whole patch set ?
