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. Related: OS#4190 Change-Id: Ia91c2f17e40fb9e79ffa5a7f28ce9c3605664402
