goldfish/events_device.c: Properly restore IRQ on load.

When restoring a snapshot, the state of the IRQ was not correctly
restored, which could sometimes end up in the inability for the
restored VM to accept any input events.

This patch fixes the issue by always setting the IRQ to the
appropriate level after the load.
