[PATCH] xen: do not map the same GSI twice
PV on HVM guests map GSIs into event channels; at restore time the
event channels are resumed by restore_pirqs.
Device drivers might try to register the same GSI again through ACPI at
restore time, but the GSI has already been mapped and bound by
restore_pirqs.
This patch detects these situations and avoid mapping the same GSI
multiple times.
