workqueue: separate out pool_workqueue locking into pwq_lock
This patch continues locking cleanup from the previous patch. It
breaks out pool_workqueue synchronization from workqueue_lock into a
new spinlock - pwq_lock. The followings are protected by pwq_lock.
* workqueue->pwqs
* workqueue->saved_max_active
The conversion is straight-forward. workqueue_lock usages which cover
the above two are converted to pwq_lock. New locking label PW added
for things protected by pwq_lock and FR is updated to mean flush_mutex
+ pwq_lock + sched-RCU.
This patch shouldn't introduce any visible behavior changes.
