workqueue: fix worker management invocation without pending works
When there's no pending work to do, worker_thread() goes back to sleep after waking up without checking whether worker management is necessary. This means that idle worker exit requests can be ignored if the gcwq stays empty. Fix it by making worker_thread() always check whether worker management is necessary before going to sleep.
