Markus Elfring c60b89aa36 USB: appledisplay: Deletion of a check before backlight_device_unregister() ...

The backlight_device_unregister() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
