function commerce_registration_update_line_item_registrations in Commerce Registration 7.3

Delete any 'unused' registrations on all line items on the order. An 'unused' registration is any registration data that doesn't belong to a specific product quantity, ie: if there are 5 registrations, but the line item only has a quantity of 4. This would be a remnant of changing the quantity after already filling out registration information. This will free up any registration space for the associated event.
