aacenc: Fix determination of Mid/Side Mode.
...
In adjust_frame_information(), msc is incremented for each sfb in each
sub-window then compared against max_sfb which is for a single sub-window.
This resulted in frames using EIGHT_SHORT_SEQUENCE where the first few
sub-windows increment msc to a value that results in ms_mode == 2. Even
though only some of the bands are actually using Mid/Side.
