Peter Hutterer 6c0d820635 mi: don't crash on miPointerGetPosition for disabled devices ...

If a device is disabled, its master device is forcibly reset to NULL but
unlike a floating device it doesn't have a sprite allocated. Calling
miPointerGetPosition for a disabled device thus crashes.

Avoid this by returning 0/0 for any device without a miPointer.
This is a quick fix only, a proper fix for this issue is rather more
involved.

Closes #1782
