selinux: fix bad cleanup on error in hashtab_duplicate()
commit 6254bd3 upstream. The code attempts to free the 'new' pointer using kmem_cache_free(), which is wrong because this function isn't responsible of freeing it. Instead, the function should free new->htable and clear the contents of *new (to prevent double-free).
