Add stack depth check to QueueFKConstraintValidation().
QueueFKConstraintValidation() recurses through the partition hierarchy
to queue child constraint validations and to mark child rows as
validated. With a sufficiently deep partition tree, this can result
in a stack-overflow crash. Defend against that as we do elsewhere.
