iommu/amd: Use protection_domain.flags to check page table mode
Page table mode (v1, v2 or pt) is per domain property. Recently we have
enhanced protection_domain.pd_mode to track per domain page table mode.
Use that variable to check the page table mode instead of global
'amd_iommu_pgtable' in {map/unmap}_pages path.
