xfrm: remove the xfrm_state_put call becofe going to out_reset

Browse Source 
commit db87668ad1e4917cfe04e217307ba6ed9390716e upstream.

This xfrm_state_put call in esp4/6_gro_receive() will cause
double put for state, as in out_reset path secpath_reset()
will put all states set in skb sec_path.

So fix it by simply remove the xfrm_state_put call.
