    cfg80211: reduce monitor interface tracking · 4290cb4b

    Revert commit b78e8cea
    ("cfg80211: track monitor channel") and remove the
    set_monitor_enabled() callback.
    
    Due to the tracking happening in NETDEV_PRE_UP, it had
    introduced bugs because the monitor interface callback
    would be called before the device was started. It looks
    like there's no way to fix this, and using NETDEV_PRE_UP
    is broken anyway (since there's no NETDEV_UP_FAIL), so
    remove all that code, track interfaces in NETDEV_UP and
    also stop tracking the monitor channel in cfg80211.
    
    This mostly reverts to before the tracking, except that
    we keep the interface count tracking so that setting the
    monitor channel can be rejected properly.
