ax25: Fix possible oops in ax25_make_new
[ Upstream commit 8c185ab6185bf5e67766edb000ce428269364c86 ] In ax25_make_new, if kmemdup of digipeat returns an error, there would be an oops in sk_free while calling sk_destruct, because sk_protinfo is NULL at the moment; move sk->sk_destruct initialization after this.
