Pavel Begunkov b4bc35cf87 io_uring: combine cq_wait_nr checks ... Instead of explicitly checking ->cq_wait_nr for whether there are waiting, which is currently represented by 0, we can store there a large value and the nr_tw will automatically filter out those cases. Add a named constant for that and for the wake up bias value.
