DINPUT device unacquire (mouse) fix

Here are a few more fixes for dinput unacquire handling. According to 
MSDN DirectInputDevice Unacquire is allowed even for devices which 
haven't been acquired yet. These patches use the current (messy) scheme 
of things.

Changelog:
- JoystickAImpl_Unacquire should return DI_NOEFFECT if the device is not
in an acquired state.
