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().
