s390/3270: Fix buffer assignment
Since commit 1b2ac5a6d61f ("s390/3270: use new address translation
helpers") rq->buffer is passed unconditionally to virt_to_dma32().
The 3270 driver allocates requests without buffer, so the value passed
to virt_to_dma32 might be NULL. Check for NULL before assigning.
