[PATCH] mm/slab_common: Use kmem_cache_free

[Vaishali Thakkar <vthakkar1994@gmail.com>]

Here, free memory is allocated using kmem_cache_zalloc.
So, use kmem_cache_free instead of kfree.

This is done using Coccinelle and semantic patch used
is as follows:

@@
expression x,E,c;
@@

 x = \(kmem_cache_alloc\|kmem_cache_zalloc\|kmem_cache_alloc_node\)(c,...)
 ... when != x = E
     when != &x
?-kfree(x)
+kmem_cache_free(c,x)
