workqueue: trivial fix for return statement in work_busy()
Return type of work_busy() is unsigned int. There is return statement returning boolean value, 'false' in work_busy(). It is not problem, because 'false' may be treated '0'. However, fixing it would make code robust. Signed-off-by: Joonsoo Kim <js1304@gmail.com> Signed-off-by: Tejun Heo <tj@kernel.org>
