When the code execute 'if (!priv->fs.arfs->wq)', the value of err is 0.
So, we use -ENOMEM to indicate that the function
create_singlethread_workqueue() return NULL.
Clean up smatch warning:
drivers/net/ethernet/mellanox/mlx5/core/en_arfs.c:373
mlx5e_arfs_create_tables() warn: missing error code 'err'.
