Remove wrong return pointer warning

I'm about to refactor part of the commit phase to use recursion instead
of iteration. As part of that change, we will no longer assign the
`return` pointer when traversing into a subtree. So I'm disabling
the internal warning that fires if the return pointer is not consistent
with the parent during the commit phase.

I had originally added this warning to help prevent mistakes when
traversing the tree iteratively, but since we're intentionally switching
to recursion instead, we don't need it.
