Yes, an extra reset. And yes, it isn't too bad.

In tg3_remove_one(), we call flush_scheduled_work() in case the
reset_task is still pending. Here, it is safe to call
flush_scheduled_work() because we're not holding the rtnl. Again, when
it runs, nothing bad will happen because it will see netif_running() ==
0.
