cube-tex: Handle SMOOTH switch case

In kmscube.c there is the following logic:

	if (mode == SMOOTH) {
		egl = init_cube_smooth(gbm);
	} else {
		egl = init_cube_tex(gbm, mode);
	}

,which makes init_cube_tex() to be never called on the SMOOTH case.

Handle the SMOOTH switch case inside init_tex() to fix the following
build warning:

cube-tex.c: In function 'init_tex':
cube-tex.c:438:2: warning: enumeration value 'SMOOTH' not handled in switch [-Wswitch]
  switch (mode) {
