Subject: Revert "scripts/gdb: add documentation example for radix tree"
This reverts commit 9b5580359a84 ("scripts/gdb: add documentation
example for radix tree")
The python implementation of radix tree was merged at the same time as a
refactoring of the radix tree implementation and doesn't work. The
feature is being reverted, thus we revert the documentation as well.
