Subject: [PATCH 03/17] workqueue: Rename __cancel_work_timer() to __cancel_timer_sync()

__cancel_work_timer() is used to implement cancel_work_sync() and
cancel_delayed_work_sync(), similarly to how __cancel_work() is used to
implement cancel_work() and cancel_delayed_work(). ie. The _timer part of
the name is a complete misnomer. The difference from __cancel_work() is the
fact that it syncs against work item execution not whether it handles timers
or not.

Let's rename it to less confusing __cancel_work_sync(). No functional
change.
