BUG/MINOR: spoa: Update pointer on the end of the frame when a reply is encoded

The same buffer is used for a request and its response. So we need to be sure
to correctly reset info when the response is encoded. And here there was a
bug. The pointer on the end of the frame was not updated.  So it was not
possible to encode a response bigger than the corresponding request.
