At the beginning of the recursive name_rev() function it creates a new 'struct rev_name' instance for each previously unvisited commit or, if this visit results in better name for an already visited commit, then updates the 'struct rev_name' instance attached to the commit, or returns early. Restructure this so it's caller creates or updates the 'struct rev_name' instance associated with the commit to be passed as parameter, i.e. both name_ref() before calling name_rev() and name_rev() itself as it iterates over the parent commits. This makes eliminating the recursion a bit easier to follow, and the condition moved to name_ref() will be moved back to name_rev() after the recursion is eliminated. This change also plugs the memory leak that was temporarily unplugged in the earlier "name-rev: pull out deref handling from the recursion" patch in this series.
