submodule-config: use hashmap_iter_first()

Browse source 
The hashmap API provides hashmap_iter_first() helper for initialion
and getting the first entry of a hashmap. Let's use it instead of
doing initialization manually and then get the first entry.

There are no functional changes, just cleanup.
