Juergen Gross a07cc0ec60 tools/xenstore: use treewalk for check_store()
Instead of doing an open tree walk using call recursion, use
walk_node_tree() when checking the store for inconsistencies.

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.
