platform/x86: asus-wmi: Fix hwmon device cleanup
The driver does not clean up the hwmon device on exit or error. To
reproduce the bug, repeat rmmod, insmod to verify that device number
/sys/devices/platform/asus-nb-wmi/hwmon/hwmon?? grows every time. Replace
call for registering device with devm_* version that unregisters it
automatically.
