io_uring: hold uring_lock when walking link chain in io_wq_free_work()
io_wq_free_work() calls io_req_find_next() from io-wq worker context,
which reads and clears req->link without holding any lock. This can
potentially race with other paths that mutate the same chain under
ctx->uring_lock.
Take ctx->uring_lock around the io_req_find_next() call. Only requests
with IO_REQ_LINK_FLAGS reach this path, which is not the hot path.
