PR KVM page fault handler performs eaddr to pte translation for a guest, however kvmppc_mmu_book3s_64_xlate() does not preserve WIMG bits (storage control) in the kvmppc_pte struct. If PR KVM is running as a second level guest under HV KVM, and PR KVM tries inserting HPT entry, this fails in HV KVM if it already has this mapping. This preserves WIMG bits between kvmppc_mmu_book3s_64_xlate() and kvmppc_mmu_map_page().
