s390/qdio: improve handling of CIWs
Fetch the individual CIWs when we actually need them, rather than
fetching both of them in qdio_setup_irq() and then needing to cache
them inside the qdio_irq.
Also deal with the error when a CIW is not available, instead of
silently dropping this error condition in qdio_setup_irq()'s caller.
