Lai Jiangshan a35780005e tracing/workqueues: Add refcnt to struct cpu_workqueue_stats ...

The stat entries can be freed when the stat file is being read.
The worse is, the ptr can be freed immediately after it's returned
from workqueue_stat_start/next().

Add a refcnt to struct cpu_workqueue_stats to avoid use-after-free.
