workqueue: more destroy_workqueue() fixes
destroy_workqueue() warnings still, at a lower frequency, trigger
spuriously. The problem seems to be in-flight operations which
haven't reached put_pwq() yet.
* Make sanity check grab all the related locks so that it's
synchronized against operations which puts pwq at the end.
* Always print out the offending pwq.
