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.

[ Impact: fix setting the wrong req-id in acpi-table parsing ]
