maple_tree: try harder to keep active node after mas_next()
Clean up the mas_next() call to try and keep a node reference when
possible. This will avoid re-walking the tree in most cases.
Also clean up the single entry tree handling to ensure index/last are
consistent with what one would expect. (returning NULL with limit of
1-oo).
