video: mx3fb: Deletion of an unnecessary check before the function call "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.
