In glancing at the HMDA guide to getting it right and by looking at the information that is reported on the LAR, I would say that you would not report the loan again.
To my knowledge there is no way to indicate on the LAR that the loan or a portion of the loan is sold.
On page 9 of the Guide to Getting it Right it states under the heading Transactions Not to be Reported:
The acquisition of only a partial interest in a home purchase or home improvement loan or a refinancing by your institution, even if you have participated in the underwriting and origination of the loan (such as in certain consortium loans).
I know you were the seller and not the buyer to it seems closely related and the closest think I found to your situation.
