kernel/cred.c: use kmem_cache_free 

Free memory allocated using kmem_cache_zalloc using kmem_cache_free rather
than kfree.

The semantic patch that makes this change is as follows:

)

// <smpl>

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)
// </smpl>
