Overwrite the device descriptor's IRQ number with whatever the legacy
driver's probe() routine fills in in nic->irqno. This is so that
non-interrupt-capable legacy drivers which set nic->irqno=0 will end
up reporting IRQ#0 via PXENV_UNDI_GET_INFORMATION; this in turn means
that the calling PXE NBP will (should) hook the timer interrupt, and
everything will sort of work.
