task_work is a LIFO list, due to how it's implemented as a lockless list. For long chains of task_work, this can be problematic as the first entry added is the last one processed. Similarly, we'd waste a lot of CPU cycles reversing this list. Wrap the task_work so we have a single task_work entry per task per ctx, and use that to run it in the right order.
