iommu/amd: Fix missing iommu_shutdown initialization in passthrough mode

Browse source 
commit f2f12b6fc0 upstream.

The iommu_shutdown callback is not initialized when the AMD
IOMMU driver runs in passthrough mode. Fix that by moving
the callback initialization before the check for
passthrough mode.
