[S390] Program check in diag 210 under 31 bit

If a virtual address is passed to the diag210 function under 31 bit, we get a
programming exception, since diag 210 only works with physical addresses. To
fix this, the content of the diag210 data structure is copied to a local
structure and the physical address of that structure is passed to diagnose 210.
