tracing: Robustify wait loop The pending nested sleep debugging triggered on the potential stale TASK_INTERRUPTIBLE in this code. While there, fix the loop such that we won't revert to a while(1) yield() 'spin' loop if we ever get a spurious wakeup. And fix the actual issue by properly terminating the 'wait' loop by setting TASK_RUNNING.
