      A patch for Bug#59022 (Valgrind warning in write_delayed() after InnoDB merge).
      
      Fix memory leak introduced by WL#5092 'RBR: Options for writing
      partial or full row images in RBR events'.
      
      Free memory which is allocated for column bitmap associated with
      each row to be processed by delayed insert handler thread.
