[PATCH spice-gtk v3 2/3] usb-redirection: do not duplicate USB device properties

[Frediano Ziglio <fziglio@xxxxxxxxxx>]

From: Yuri Benditovich <yuri.benditovich@xxxxxxxxxx>

Do not keep bus, address, vid and pid of the USB device
in SpiceUsbDeviceInfo structure. Getters for these properties
can easily obtain them from respective backend device.
