Subject: [PATCH 1/2] HID: redragon: Fix regression in non-Redragon keyboard
 due to this new driver

The Redragon keyboard uses the second device being presented, but other
devices with the same vendor_id/device_id pair (0x0c45:760b) use the first.
Don't cause its deletion. Problem introduced in commit 85455dd906d5
("HID: redragon: Fix modifier keys for Redragon Asura Keyboard")

Fixes: 85455dd906d5
