Actually, I do not. It looks like an optimization: if the device is
throttled we just do not need to add timer, qdisc will be woken up
by unthrottle. I do not see any race condition here, but also I do not
see why this check could be important.

To be honest, I wish to be reminded. If this check cured something,
it would be interesting to know what was this.
