util.dataforms: Skip all fields for the 'cancel' form type XEP-0004 says: > a data form of type "cancel" SHOULD NOT contain any <field/> elements. The title and instructions don't seem to be of much value in this case either. I'm not aware of 'cancel' being used anywhere, so this should break nothing. Early return is always nice.
