iwlwifi: fix kernel crash when unregistering thermal zone [ Upstream commit 92549cdc288f47f3a98cf80ac5890c91f5876a06 ] A recent firmware change seems to have enabled thermal zones on the iwlwifi driver. Unfortunately, my device fails when registering the thermal zone. This doesn't stop the driver from attempting to unregister the thermal zone at unload time, triggering a NULL pointer deference in strlen() off the thermal_zone_device_unregister() path. Don't unregister if name is NULL, for that case we failed registering. Do the same for the cooling zone.
