[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.
