[gnome-control-center] display: Silence -Wmaybe-uninitialized

[Debarshi Ray <debarshir src gnome org>]

commit 63bf6aaf4b2569c366438d9265089b4f76145540
Author: Debarshi Ray <debarshir gnome org>

    display: Silence -Wmaybe-uninitialized
    
    We create rotate_box only when show_rotation is TRUE, and the
    conditions for checking the different kinds of rotation do not make
    sense when show_rotation is FALSE.
