Commit a8091f039c1e ("maple_tree: add MAS_UNDERFLOW and MAS_OVERFLOW states") adds more status during maple tree walk. But it introduce a typo on the status check during walk.
It expects to mean neither active nor start, we would restart the walk, while current code means we would always restart the walk.
