Fix Clang 18.0.0 -Wunreachable-code warnings

Clang 18.0.0 warns about the following code:

    const int row_scale = mi_size_high[BLOCK_16X16] == 2 ? 1 : 2;
    const int col_scale = mi_size_wide[BLOCK_16X16] == 2 ? 1 : 2;

because the conditional expressions are false.

This code was originally added in
https://aomedia-review.googlesource.com/c/aom/+/9721. At that time,
mi_size_high[BLOCK_16X16] and mi_size_wide[BLOCK_16X16] could be either
4 or 2 depending on whether CONFIG_CB4X4 was 1 or 0. Now
mi_size_high[BLOCK_16X16] and mi_size_wide[BLOCK_16X16] are equal to 4.
