Ondrej Mosnacek 0f71433eb7 selinux: fix bad cleanup on error in hashtab_duplicate()
commit 6254bd3db3 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).
