  [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.
