tls: stop recv() if initial process_rx_list gave us non-DATA

Browse source

[ Upstream commit fdfbaec592 ]

If we have a non-DATA record on the rx_list and another record of the
same type still on the queue, we will end up merging them:
 - process_rx_list copies the non-DATA record
 - we start the loop and process the first available record since it's
   of the same type
 - we break out of the loop since the record was not DATA

Just check the record type and jump to the end in case process_rx_list
did some work.
