[PATCH spice-gtk 08/44] fixup! usb-redir: define interfaces to support emulated devices

[Frediano Ziglio <fziglio@xxxxxxxxxx>]

Unify spice_usb_device_get_description and spice_usb_backend_device_description
They were doing the same thing.
This make spice_usb_backend_device_description more consistent
supporting any device, not only emulated
