Windows: WinUSB: Guard against erroneous reporting of devices
During enumeration, obtaining the port number via SPDRP_ADDRESS might
return a bogus value for some third-party HCD drivers. If this occurs,
we might end up reporting the device as having the VID/PID from the last
successful enumeration. Guard against this particular situation by
clearing the USB_NODE_CONNECTION_INFORMATION_EX structure before issuing
the DeviceIoControl() call.
