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.
