[spice-gtk 08/13] usb-redir: change signal prototype of win-usb-dev

[Yuri Benditovich <yuri.benditovich@xxxxxxxxxx>]

Changing signal definition from (boxed-boxed) to (pointer,int).
There is no need for additional referencing of GUdevDevice
object before signal callback. Second parameter (action) is
0 for device removal and 1 for device addition.
