[RFC v4 01/12] kthread: Add kthread_queue_flush_work()

Currently, it's only possible to flush on a kthread_work in contexts where it's possible to block. This can be kind of painful though when trying to implement new types of delayed work which use kthread_work, since it means we'd need to drop any spinlocks for new delayed work implementations before
