      BUG#11766440 - 59546: ASSERTION M_SP == __NULL
      FAILS IN ITEM_FUNC_SP::INIT_RESULT_FIELD WITH FU
      
      Post push patch for fixing the failing partitioning debug tests.
      
      Reopen of tables under LOCK TABLES would fail, since
      an error was already set.
      
      Fixed by using a temporary Diagnostics_area during
      reopen of locked tables.

No bundle (reason: useless for push emails).
