svga: Keep tight control of texture handle ownership.

The texture owns the surface handle. All derivatives need to keep
a reference to texture.

This fixes several assertions failures starting up Jedi Knight 2.

Should cause no change for DRM surface sharing -- reference count still
done as before there.
