Subject: workqueue: Fix workqueue lockdep name
Tommi noticed a 'funny' lock class name: "%s#5" from a lock acquired in
process_one_work(). It turns out that commit b196be89cdc14 forgot to
change the lockdep_init_map() when it changed the @lock_name argument
from a string to a format.
Fixes: b196be89cdc14 ("workqueue: make alloc_workqueue() take printf fmt and args for name")
