    Fix xfdesktop --reload in spanning mode (Bug 10853)

    When issuing an xfdesktop --reload while in spanning wallpaper
    mode, all the monitors would update their backdrop which means
    the wallpaper of the last monitor would then be shown. This
    fixes the logic to continue to show the wallpaper for the first
    monitor as intended.
