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.
