As far as I understand, this is supposed to be filled by BuildActionMap. If
it's GUID_NULL then it simply failed to match any device object and it is
unmapped.

Then mayb the game doesn't call BuildActionMap and expects SetActionMap to
re-do the matching, or to match nonetheless. I'll write a few tests to check
that.
