[PATCH v3] workqueue: Fix double kfree for rescuer

[qiang.zhang]

From: Zhang Qiang <qiang.zh...@windriver.com>

The callback function "rcu_free_wq" could be called after memory
was released for "rescuer" already, Thus delete a misplaced call
of the function "kfree".

Fixes: 6ba94429c8e7 ("workqueue: Reorder sysfs code")
