Shouldn't be, if done right.  If the interrupt runs a TX completion 
cycle, it will run the code
	if (work_done && netif_queue_stopped(dev))
		netif_wake_queue(dev)

Since ->hard_start_xmit is guaranteed never to be called if the queue is 
stopped, you also guaranteed that netif_wake_queue and ->hard_start_xmit 
are mutually exclusive.

This of course assumes certain details about the driver implementation, 
which may be missing from that driver's TX completion handler :)

Thanks for your, and everybody else's comments.  They are being saved.
