[1-3] are shedding excessive locking of @wqe's and @worker's spinlocks from io_worker_handle_work(). [4] removes an extra pair of refcount get/put by making former io_put_work() to own the submission reference. It also changes io-wq get/put API and renames io_put_work() into io_free_work() to reflect it.
