tools/xenstore: use treewalk for deleting nodes

Instead of doing an open tree walk using call recursion, use
walk_node_tree() when deleting a sub-tree of nodes.

This will reduce code size and avoid many nesting levels of function
calls which could potentially exhaust the stack.

This is part of XSA-418 / CVE-2022-42321.
