This behavior is different than all other code paths. This patch corrects that by down'ing the device and then scheduling the sfp_config_module_task tasklet. The tasklet will detect this condition (like it does with other code paths) and do the unregister_netdev(). I also removed the log message as this condition (an unsupported SFP+ module) will be logged in sfp_config_module_task.
