tdef: fixup osmo_tdef_set()
I missed code review, so here are my comments in form of a follow-up patch
for Id56a1226d724a374f04231df85fe5b49ffd2c43c.
- Fix 'as_unit' arg name to 'val_unit' as in the C file and API doc.
- Explain rounding-up behavior of value conversion in API doc.
- Use osmo_tdef_get_entry() instead of a loop.
