kthread_work: remove the unused wait_queue_head The wait_queue_head_t kthread_work->done is unused since flush_kthread_work() has been re-implemented. Let's remove it including the initialization code. This makes DEFINE_KTHREAD_WORK_ONSTACK() unnecessary, removed. tj: Updated description. Removed DEFINE_KTHREAD_WORK_ONSTACK().
