wined3d: Use surface_modify_location() to manipulate location flags in IWineD3DSurfaceImpl_Unmap(). 

Directly setting SFLAG_INFRAWABLE breaks for offscreen render targets, where
the drawable and texture are the same thing. Before commit
d3fd7b247b the explicit load of the texture
location with the default RTL_READTEX render target lock mode would have
prevented the flags from becomming inconsistent.
