[PATCH 0/1] MR8419: ddraw: Fix use-after-free of the ddraw object.

[Yuxuan Shui (＠yshui)]

ddraw surfaces also hold references to their ddraw objects, but that's not
cleared in ddraw_destroy.

not sure if other uses of surface->ddraw need to be guarded too, let me know if i need to change them too.
