Subject[PATCH v2] x86: remove redundant check for kmem_cache_create()
Date
The flag 'SLAB_PANIC' implies panic when encouter failure,
So there is no need to check NULL pointer for cache creation.

Signed-off-by: Chengguang Xu <cgxu519@gmx.com>

v1->v2:
- Keep return type as int instead of changing to void.
