When toggle_irq is called for PCI devices to disable device interrupts it used tasklet_disable to wait for a possibly running tasklet to finish. However, on SMP systems the tasklet might still be scheduled on another CPU. Instead, use tasklet_kill to ensure that all scheduled tasklets are finished before returning from toggle_irq. Furthermore, it was possible that a tasklet reenabled its interrupt even though interrupts have been disabled already. Fix this by checking the DEVICE_STATE_ENABLED_RADIO flag before reenabling single interrupts during tasklet processing. While at it also enable/kill the TBTT and PRETBTT tasklets in the toggle_irq callback and only use tasklet_kill in stop_queue to wait for a currently scheduled beacon update before returning.
