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

Browse Source 
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.
