[gnome-settings-daemon] power: Remove unnecessary min variables

[Bastien Nocera <hadess src gnome org>]

    power: Remove unnecessary min variables
    
    There is no need to use min variable anymore, as it's always set to 0.
    If we were to revert this because we need a different minimum, note that
    the related bug contains bug fixes for cases where min should have been
    used but was not.
