Subject: [PATCH] xfrm: properly handle invalid states as an error
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The error exit path needs err explicitly set. Otherwise it
returns success and the only caller, xfrm_output_resume(),
would oops in skb_dst(skb)->ops derefence as skb_dst(skb) is
NULL.

Bug introduced in commit bb65a9cb (xfrm: removes a superfluous
check and add a statistic).
