iommu/amd: Fix sleeping in atomic context

Browse source

Commit cf70873e3d ("iommu/amd: Refactor GCR3 table helper functions")
changed GFP flag we use for GCR3 table. Original plan was to move GCR3
table allocation outside spinlock. But this requires complete rework of
attach device path. Hence we didn't do it as part of SVA series. For now
revert the GFP flag to ATOMIC (same as original code).
