HID: asus: Remove check for same LED brightness on set

commit 094ca9075e8b8af73e8dcf81ca7edb304cc86a83 upstream.

Remove the early return on LED brightness set so that any controller
application, daemon, or desktop may set the same brightness at any stage.

This is required because many ASUS ROG keyboards will default to max
brightness on laptop resume if the LEDs were set to off before sleep.
