[Patch v3 2/3] maple_tree: restart walk on correct status

[Wei Yang]

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.
