s390/qdio: don't allocate *aob array with GFP_ATOMIC
The only way to reach this allocation is via
qdio_establish()
qdio_detect_hsicq()
qdio_enable_async_operation()
and since qdio_establish() uses wait_event_*() just a few lines ealier,
we can trust that it certainly is never called from atomic context.
