Subject: [PATCH 3/4] tracing/workqueue: Use list_for_each_entry instrad of
 list_for_each_entry_safe in probe_workqueue_destruction()

No need to use list_for_each_entry_safe() because we just remove one list node
which is first found in list iteration.
(we don't continue list iteration after remove list node)
