Subject: Warning is now gone...

As discussed, here is the warning removal, which I have checked
into net-2.6

It really was putting the cart before the horse, because
one should provide a sane alternative before making something
illegal :-)

I'll try to come up with a usable netif_tx_{free,unfreeze}()
set of interfaces.

netdev: Remove warning from __netif_schedule().

It isn't helping anything and we aren't going to be able to change all
the drivers that do queue wakeups in strange situations.

Just letting a noop_qdisc get scheduled will work because when
qdisc_run() executes via net_tx_work() it will simply find no packets
pending when it makes the ->dequeue() call in qdisc_restart.
