ACPI/IORT: Move the check to get iommu_ops from translated fwspec
With IOMMU probe deferral, iort_iommu_configure can be called multiple times for the same device. Hence we have a check to see if the device's fwspec is already translated and return the iommu_ops from that directly. But the check is wrongly placed in iort_iommu_xlate, which breaks devices with multiple sids. Move the check to iort_iommu_configure.
