xfrm_user: fix info leak in copy_to_user_policy() The memory reserved to dump the xfrm policy includes multiple padding bytes added by the compiler for alignment (padding bytes in struct xfrm_selector and struct xfrm_userpolicy_info). Add an explicit memset(0) before filling the buffer to avoid the heap info leak.
