HID: logitech-hidpp: Don't use the USB serial for USB devices

[ Upstream commit 7ad1fe0da0fa91bf920b79ab05ae97bfabecc4f4 ]

For devices that support the 0x0003 feature (Device Information) version 4,
set the serial based on the output of that feature, rather than relying
on the usbhid code setting the USB serial.

This should allow the serial when connected through USB to (nearly)
match the one when connected through a unifying receiver.

For example, on the serials on a G903 wired/wireless mouse:
- Unifying: 4067-e8-ce-cd-45
- USB before patch: 017C385C3837
- USB after patch: c086-e8-ce-cd-45
