    HID: logitech-hidpp: Reconcile USB and Unifying serials
    
    [ Upstream commit 5b3691d15e04b6d5a32c915577b8dbc5cfb56382 ]
    
    Now that USB HID++ devices can gather a serial number that matches the
    one that would be gathered when connected through a Unifying receiver,
    remove the last difference by dropping the product ID as devices
    usually have different product IDs when connected through USB or
    Unifying.
    
    For example, on the serials on a G903 wired/wireless mouse:
    - Unifying before patch: 4067-e8-ce-cd-45
    - USB before patch: c086-e8-ce-cd-45
    - Unifying and USB after patch: e8-ce-cd-45
