Changelog: 

Initialize parent_iter to prevent clang-analyzer from complaining.

In fact, it's not a problem. If the node is not a group, then it
has a group as a parent. If it is a group, then sort_method_none
will be called, which checks node->parent before using the iter.
But clang-analyzer can't know these things.
