[PATCH v6 02/11] revision: parse parent in indegree_walk_step()

From: Abhishek Kumar <redacted>

In indegree_walk_step(), we add unvisited parents to the indegree queue.
However, parents are not guaranteed to be parsed. As the indegree queue
sorts by generation number, let's parse parents before inserting them to
ensure the correct priority order.
