[PATCH 2/8] wined3d: Deactivate the device before minimizing the window.

[Stefan Dösinger]

This fixes tabbing out of Deus Ex Game of the Year edition.

This patch ignores that d3d9 has different behavior than ddraw. D3d9's
behavior matches what we currently have (the device state during focus
loss is D3DERR_DEVICENOTRESET, and only the final WM_ACTIVATEAPP message
has D3DERR_DEVICELOST). This could be handled via a create flag. I am
not doing it for now because I think it is less likely for a d3d9 app to
depend on it (you can't destroy the device until the very end, but still
can't do anything due to D3DERR_DEVICENOTRESET).
