      Bug #43913  rpl_cross_version can't pass on conflicts complainig clash with
      --slave-load-tm
            
      The MDL_SHARED lock was introduced for an object in 5.4, but the 'TABLE_LIST' 
      object was not initialized with the MDL_SHARED lock when applying event with 
      LOAD DATA INFILE into table. So the failure is caused when checking the 
      MDL_SHARED lock for the object.
      To fix the problem, the 'TABLE_LIST' object was initialized with the MDL_SHARED 
      lock when applying event with LOAD DATA INFILE into table.
     @ mysql-test/suite/rpl/t/disabled.def
        Got rid of the line for enabling 'rpl_cross_version' test.
