[PATCH]: set state to XFRM_STATE_DEAD before calling xfrm_state_put in pfkey_msg2xfrm_state

This patch sets x->state to XFRM_STATE_DEAD before calling
xfrm_state_put in pfkey_msg2xfrm_state to avoid triggering
the BUG_TRAP in __xfrm_state_destroy. The patch applies to both
2.5 and the 2.4 backport.

Best regards,
Patrick
