Nico Boehr 58635d6615 s390/mm: fix virtual-physical address confusion for swiotlb
swiotlb passes virtual addresses to set_memory_encrypted() and
set_memory_decrypted(), but uv_remove_shared() and uv_set_shared()
expect physical addresses. This currently works, because virtual
and physical addresses are the same.

Add virt_to_phys() to resolve the virtual-physical confusion.
