HID: asus: early return for ROG devices

Some ROG devices have a new dynamic backlight interface for control by
Windows. This interface does not create an ->input device, causing the
kernel to print an error message and to eject it. In addition, ROG
devices have proper HID names in their descriptors so renaming them is
not necessary.

Therefore, if a device is identified as ROG, early return from probe to
skip renaming and ->input checks.
