e1000e: Prevent MSI/MSI-X storms
Only signal MSI/MSI-X events on rising edges. So far we re-triggered the interrupt sources even if the guest did no consumed the pending one, easily causing interrupt storms. Issue was observable with Linux 4.16 e1000e driver when MSI-X was used. Vector 2 was causing interrupt storms after the driver activated the device.
