[PATCH v3] submodule-config: use hashmap_iter_first()

From: Alexander Kuleshov <kuleshovmail@gmail.com>
Date: Mar 16, 2016, 07:46 UTC
Message-ID: <1458114391-2235-1-git-send-email-kuleshovmail@gmail.com>

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.
