[autofit] Reset the face charmap directly.

There is no need to validate the original charmap in `FT_Set_Charmap`.
It can be reset directly.

* src/autofit/afglobal.c (af_face_globals_compute_style_coverage):
Use direct assignment.
* src/autofit/af{latin,cjk,indic}.c (af_latin_metrics_init): Ditto.
