Subject: [PATCH] workqueue: Move the position of debug_work_activate() in
__queue_work()
[ Upstream commit 0687c66b5f666b5ad433f4e94251590d9bc9d10e ]
The debug_work_activate() is called on the premise that
the work can be inserted, because if wq be in WQ_DRAINING
status, insert work may be failed.
Fixes: e41e704bc4f4 ("workqueue: improve destroy_workqueue() debuggability")
