    texture-pixmap-x11: set ->winsys = NULL if _create fails
    
    If _cogl_winsys_texture_pixmap_x11_create() fails then implicitly no
    private state has been associated with the given tex_pixmap. Since that
    winsys isn't associated with it we explicitly set tex_pixmap->winsys =
    NULL.
