[PATCH] s390: dasd wait for clear i/o interrupt
The sleep_on function clears a running cqr without waiting for the related
interrupt. This can lead to a panic at the time the interrupt is processed
because the related memory might already be freed. Wait for clear-interrupt
and de-queue cqr prior to return.
