Very late answer, but: we don't need to call qemu_set_irq() on
qemu_irqs outbound from a device after a vmload, because IRQ
lines themselves have no state. The device on the other end of
the irq line also loads its own state, and typically that includes
its internal variables which it uses to track whether its input
lines are 0 or 1.
