[ Upstream commit 22537c9f79417fed70b352d54d01d2586fee9521 ]
io_task_work_pending() uses wq_list_empty() on ctx->work_llist, but it's not an io_wq_work_list, it's a struct llist_head. They both have ->first as head-of-list, and it turns out the checks are identical. But be proper and use the right helper.
