 ticket: 6379
 subject: Fix possible free of uninitialized value in walk_rtree
 tags: pullup
 target_version: 1.7

 In rtree_hier_realms, if the first rtree_hier_tweens call failed, the
 cleanup handler would free stweens which had not been initialized.
 Initialize ctweens and stweens to NULL in the variable declarations to
 make the cleanup handler safe.
