[PATCH 3/4] user32: Update rawinput device list in WM_DEVICECHANGE callback.

[Rémi Bernon]

The SDL library calls GetRawInputDeviceList quickly after it has
detected a new device, from a WM_DEVICECHANGE notification.

It uses rawinput device information to find out whether it is an XInput
device, when its name contains "IG_", or if the device should be opened
through DInput.

If the device is missing from the rawinput list, it considers it as a
DInput device, and may end up with the same device used twice.
