Fix function_clause when sending a request after an outgoing DPA

After DPR, the intention is that outgoing answers are sent and outgoing
requests are discarded. This was the case when the DPR was outgoing, but
if it was incoming then a subsequent outgoing request resulted in a
function_clause, bringing down the diameter_peer_fsm gen_server
associated with the transport connection in question.

With diameter_tcp/sctp, the failure can result in the connection being
reset before the peer closes it in response to DPA, but is otherwise
harmless since DPR means that the connection is already on its way down.
