BUG#17233 : LOAD DATA INFILE: failure causes mysqld dbug_assert, binlog not flushed

This patch corrects a bug involving a LOAD DATA INFILE operation on a 
transactional table. It corrects a problem in the error handler by moving
the transactional table check and autocommit_or_rollback operation to the 
end of the error handler. 

The problem was an assert was thrown after the operation completed. The 
assert found a non-sunk event in the transaction cache. The events in the 
transaction cache were added after commit_or_rollack and thereafter nothing 
removed them.

An additional test case was added to detect this
condition.

  BUG#17233 : LOAD DATA INFILE: failure causes mysqld dbug_assert, binlog not flushed 
      
  This patch adds an additional test to rpl_loaddata for handling the
  duplicate key error on LOAD DATA INFILE.

  BUG#17233 : LOAD DATA INFILE: failure causes mysqld dbug_assert, binlog not flushed 
      
  This patch adds the results for the additional test for properly handling the
  duplicate key error on LOAD DATA INFILE.
sql/sql_load.cc:
  BUG#17233 : LOAD DATA INFILE: failure causes mysqld dbug_assert, binlog not flushed 
  
  This patch moves the check for a transactional table and rollback in the
  error handler for mysql_load(). The patch moves the transactional table
  check to the end of the error handler matching the implementation for other
  similar operations (see sql_insert).
