s390/qdio: rework q->qdio_error indication

Browse source

When inspecting a queue, any error is currently returned back through
the queue's qdio_error field. Turn this into a proper variable that gets
passed through the call chain, so that the lifetime is clear and the
error state can be accessed along the way.
