Minimal ddraw1.c file to reproduce the crash

The ddraw1 crash happens in restore_surfaces() call, even if restore_callback()
does nothing at all.

However further investigation shows that neither the removed set_display_mode()
call, nor the lines added by 7cabef14 matter: I came up with a minimal test
that reliably produces the same crash.

What the driver does not like is the DDSCAPS_COMPLEX | DDSCAPS_FLIP |
DDSCAPS_TEXTURE CreateSurface() combination.
