[autofit] Fix potential memory leak.

Browse Source 
While this doesn't show up with FreeType, exactly the same code
leaks with ttfautohint's modified auto-hinter code (which gets used
in a slightly different way).

It certainly doesn't harm since it is similar to already existing
checks in the code for embedded arrays.

* src/autofit/afhints.c (af_glyph_hints_reload): Set `max_contours'
and `max_points' for all cases.
