Subject: xfrm: properly handle invalid states as an error

From: Timo Teräs <[email protected]>

[ Upstream commit 497574c72c9922cf20c12aed15313c389f722fa0 ]

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).
