iommu/amd: Do not try copy old DTE resume path
In suspend/resume path, no need to copy old DTE (early_enable_iommus()).
Just need to reload IOMMU hardware.
This is the side effect of commit 3ac3e5ee5ed5 ("iommu/amd: Copy old
trans table from old kernel") which changed early_enable_iommus() but
missed to fix enable_iommus().
Resume path continue to work as 'amd_iommu_pre_enabled' is set to false
and copy_device_table() will fail. It will just re-loaded IOMMU. Hence I
think we don't need to backport this to stable tree.
