rdppm.c: Fix innocuous MSan error A fuzzing test case that was effectively a 1-pixel PGM file with a maximum value of 1 and an actual value of 8 caused an uninitialized member of the rescale[] array to be accessed in get_gray_rgb_row() or get_gray_cmyk_row(). Since, for performance reasons, those functions do not perform bounds checking on the PPM values, we need to ensure that unused members of the rescale[] array are initialized.
