netdev: Do not leak netdev objects 

If the daemon is started and killed rapidly on startup, it is possible
for netdev_shutdown to be called prior to manager processing messages
that actually create the netdev itself.  Since the netdev_list has
already been freed, the storage is lost.  Fix that by destroying
netdev_list only when the module is unloaded.
