>Description:
In working on fixing the comparator problem in PR-43488, I noticed that there 
is an inconsistency in rb_tree_find_node_geq and rb_tree_find_node_leq.

Based on the inverted nature of these two functions, one would assume their 
search pattern would be simply inverted, but it looks like their is a 
copy/paste bug in choosing the next node to look at in the itteration.

>How-To-Repeat:
I haven't created a test case.  It seems obvious by observation.
>Fix:
Change the comparator of one of them... not sure which to say because the 
comparators are currently inverted as it is (PR-43488),
