[PATCH] dinput: Use the same GUID for Instance and Product

[Brendan McGrath]

This matches the behaviour of DirectInput8 native and appears to be
required for some games to recognise the mouse and keyboard as
a mouse and keyboard.
---

I had a game that worked correctly with dinput native but not with built-in.

I wrote a simple program that ran the IDirectInput8::EnumDevices method
and found that dinput8=b vs dinput8=n gave different results.

One of the differences was that the Instance and Product GUID were the same in
native.

After applying this patch - the game started working correctly with built-in.
