[PATCH] workqueue: remove unnecessary goto statement

[Libin <huawei.libin@huawei.com>]

Using return NULL to replace goto statement and avoiding a redundant
function call for free_workqueue_attrs(). If kzalloc for attrs of
struct workqueue_attrs is failed, alloc_workqueue_attrs return
NULL directedly. With no functional changs.
