MDEV-12078 Using spatial index changes type from point to geometry

Browse source 
In get_mm_tree we have to change Field_geom::geom_type to
        GEOMETRY as we have to let storing all types of the spatial features
        in the field. So now we restore the original geom_type as it's
        done.
