ACPI: scan: Move misleading comment to acpi_dma_configure_id()
The acpi_iommu_configure_id() implementation has a misleading comment since after it the flow does something different to what it states. Move the commit to the caller and with that unshadow the error code inside acpi_iommu_configure_id(). Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
