If we're in interrupt mode and live migrating a guest, there is a window
where the I/O queues haven't been set up but the device is in running
state, during which the guest might write to a doorbell. This doorbell
write will go unnoticed. This patch ensures that we re-check the
doorbells after an I/O queue has been set up.
Fixes#2410
