mhlsbr.c: Don't hide mhladios and mhldone behind macros.

Locally defined mhladios() and mhldone() were called as adios() and
done() thanks to #defines that hid the widely-used functions with those
names.  Don't bother as it confuses the reader.  Just call the local
variations directly to make clear it's not the standard implementation.
