s390/cio: sort out physical vs virtual pointers usage
This does not fix a real bug, since virtual addresses
are currently indentical to physical ones.
Use virt_to_phys() for intparm interrupt parameter to
convert a 64-bit virtual address to the 32-bit physical
address, which is expected to be below 2GB.
