pxe: Add code to detect a struck interrupt line and disable (go to poll)
Add code to detect a stuck interrupt line and disable it; at that
point we will go to polling mode. Currently we only give ourselves 3
timer ticks after initialization to detect this, but this is good
enough to deal with gPXE on virtio.
