Make sure we set TASK_QUEUED in every case before adding the task to the run queue. task_wakeup() now checks if either TASK_QUEUED or TASK_RUNNING is set, and if neither is set, add TASK_QUEUED and effectively add the task to the runqueue. No longer use __task_wakeup() anywhere except in task_wakeup(), always use task_wakeup() instead. With the old code, process_runnable_task() may re-add a task in the runqueue without setting the TASK_QUEUED flag, and there were race conditions that could lead to a task having the TASK_QUEUED flag but not in the runqueue, thus being unschedulable. This should be backported to 1.9.
