Bug #26261:

 INSERT uses query_id to verify what fields are
 mentioned in the fields list of the INSERT command.
 However the check for that is made after the 
 ON DUPLICATE KEY is processed. This causes all
 the fields mentioned in ON DUPLICATE KEY to be 
 considered as mentioned in the fields list of 
 INSERT.
 Moved the check up, right after processing the
 fields list.
