blkdebug: reschedule coroutine on the AioContext it is running on
Keep the coroutine on the same AioContext. Without this change,
there would be a race between yielding the coroutine and reentering it.
While the race cannot happen now, because the code only runs from a single
AioContext, this will change with multiqueue support in the block layer.
While doing the change, replace custom bottom half with aio_co_schedule.
