iommu/amd: Pass gfp flags to iommu_map_page() in amd_iommu_map()
A recent commit added a gfp parameter to amd_iommu_map() to make it
callable from atomic context, but forgot to pass it down to
iommu_map_page() and left GFP_KERNEL there. This caused
sleep-while-atomic warnings and needs to be fixed.
