[DINPUT] Fix some stupid game :-)

[Lionel Ulmer <lionel.ulmer@free.fr>]

Hi all,

Some games only Acquire the mouse device *if* we return an error on
GetDeviceData when the mouse in unacquired...

So report this error as we should :-)

Changelog:
 Report an error if GetDeviceData is called on an Unacquired device
