[netdevice] Stop link block timer when device is closed
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.)
