    Stop copying displayed partition objects in activate_resize() (#750168)
    
    The first actions of Win_GParted::activate_resize() were to create a
    copy of the vector of partitions for the currently displayed device and
    visually apply any pending operations.  Exactly this has already been
    done in Win_GParted::Refresh_Visual() with the result now available in
    the member variable display_partitions.  Stop this unnecessary partition
    object copying and processing by just using display_partitions member
    variable instead.
