atl2: don't request irq on resume if netif running
If the device is suspended with the cable disconnected, then
resumed with the cable connected, dev->open is called before
resume. During resume, we request an IRQ, but the IRQ was
already assigned during dev->open, resulting in the warning
shown below.
Don't request an IRQ if the device is running.
