Subject: [PATCH] HID: asus: add missing code in asus_event

From: Pei Xiao <xiaopei01@...inos.cn>

In the commit f631011e36b8 ("HID: hid-asus: Implement fn lock for Asus
ProArt P16"), there was FN-related code for asus_event, but in the latest
linux-next branch, the FN code for asus_event is missing. So add it.
