s390/qdio: simplify thinint device registration
On an interrupt, tiqdio_thinint_handler() walks a list of all objects
that might require attention, and checks their DSCI. This list is
awkwardly built from Input Queues, even though the IRQs are per-device
and the queue is then only used to dereference its qdio_irq parent.
To simplify the logic, change the code so that tiq_list contains
qdio_irq entries.
