Subject: [PATCH] xfrm: Use kmem_cache_zalloc() instead of kmem_cache_alloc() with flag GFP_ZERO.

From: Huang Zijiang <huang.zijiang@....com.cn>

Use kmem_cache_zalloc instead of manually setting kmem_cache_alloc
with flag GFP_ZERO since kzalloc sets allocated memory
to zero.

Change in v2:
     add indation
