This actually adds a bug back into the code. We're trying to work out how to cleanly break out of the net_rx_action() ->poll() loop when a device is brought down yet getting hammered with packets. I'll try to devote some time to this over the weekend, meanwhile just toss this patch, we know it's an issue that all the drivers need to get audited for but we can't fix that until the above paragraph stuff is worked out.

This eliminates any chance that myri10ge_poll() can trigger an oops by calling netif_rx_complete() and returning with work_done == budget.
