xfs: elide defer work ->create_done if no intent

Christoph pointed out that the defer ops machinery doesn't need to call
->create_done if the deferred work item didn't generate a log intent
item in the first place.  Let's clean that up and save an indirect call
in the non-logged xattr update call path.

This has been lightly tested with fstests.  Enjoy!
