      Bug#40515: Query on a partitioned table does not return
      'lock wait timeout exceeded'
      
      Problem was a bug in the implementation of scan in partitioning
      which masked the error code from the partition's handler.
      
      Fixed by returning the value from the underlying handler.

    Removing redeclaration of result variable,
    which resulted in never returning the correct return value.
