      Fix for BUG#32880 - Repairing Archive table fails with internal error 144
      
      Repairing Archive table fails as the row read from the corrupted archive 
      table is not equal the length at the time of insert
      
      The assertion is not valid anymore and removed it to avoid the server
      crash
      
      Corrupted Archive tables cannot be repaired.
