wined3d: Remove texture locations after unloading all subresources.

The problem is that surface_unload calls wined3d_texture_force_reload, which
invalidates the texture location of all mipmaps and not just the one that was
unloaded. If the other mipmaps only have a valid texture copy, which is quite
likely, they are lost.

The attached patch changes this behavior and controls the invalidation of the
texture location from the container, which is also the place where the GL
texture is actually deleted. Ideally we should call unload only on containers
and not on subresources. I am not yet sure if the attached patch has any
negative side effects because of that.
