This stops the stack from hitting us with transmits while we're shutting down. Additionally, disable NAPI before disabling interrupts, or the interrupt might get re-enabled inappropriately. Finally, remove the call to netif_tx_stop_all_queues, as it is redundant - the call to netif_tx_disable already did the same thing.
