s390/vmur: fix virtual vs physical address confusion
Add missing virt_to_phys() / phys_to_virt() translation to alloc_chan_prog() and free_chan_prog(). This doesn't fix a bug since virtual and physical addresses are currently the same. Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Signed-off-by: Heiko Carstens <hca@linux.ibm.com>
