El km.state no se comprueba en el trabajo retrasado del controlador. Cuando se llama a xfrm_state_check_expire(), el estado se puede restablecer a XFRM_STATE_EXPIRED, incluso si ya est\u00e1 XFRM_STATE_DEAD. Esto sucede cuando se elimina el estado de xfrm, pero a\u00fan no se libera. Cuando se vuelve a llamar a __xfrm_state_delete() en el temporizador de xfrm, se produce el siguiente fallo. Para solucionar este problema, omita xfrm_state_check_expire() si km.state no es XFRM_STATE_VALID.
