    [sfnt] Fix off-by-one error.
    
    The 0-base index is equal to the number of previosly parsed entries.
    It is an error to adjust it by one to get the number truncated by
    a stream error.  This is probably inconsequential because valid
    entries are correctly accounted for.
    
    * src/sfnt/ttload.c (check_table_dir): Do not adjust the truncated
    number of tables.
