All defer op instance place their own extension of the log item into the dfp_done field. Replace that with a xfs_log_item to improve type safety and make the code easier to follow. Also use the opportunity to improve the ->finish_item calling conventions to place the done log item as the higher level structure before the list_entry used for the individual items.
