maple_tree: fix freeing of nodes in rcu mode

Browse source

commit 2e5b4921f8 upstream.

The walk to destroy the nodes was not always setting the node type and
would result in a destroy method potentially using the values as nodes.
Avoid this by setting the correct node types.  This is necessary for the
RCU mode of the maple tree.
