[ impact: set flags for the right req-id in the device table ]
The devid parameter to set_dev_entry_from_acpi is the requester ID rather than the device ID since it is used to index the IOMMU device table. The handling of IVHD_DEV_ALIAS used to pass the device ID. This patch fixes it to pass the requester ID.
