A running link block timer holds a reference to the network device and will prevent it from being freed until the timer expires. It is impossible for free_netdev() to be called while the timer is still running: the call to stop_timer() therein is therefore a no-op. Stop the link block timer when the device is closed, to allow a link-blocked device to be freed immediately upon unregistration of the device. (Since link block state is updated in response to received packets, the state is effectively undefined for a closed device: there is therefore no reason to leave the timer running.)
