    gvdb test: fix logic for infinite walks
    
    We were using a negative variable for the value of a counter designed to
    bound the number of open() calls in a walk.  We were decrementing it in
    that case (which is fine since it would never reach zero again anyway).
    It was a bit ugly, though.
