rxrpc: Fix loss of final ack on shutdown
Fix the loss of transmission of a call's final ack when a socket gets shut
down. This means that the server will retransmit the last data packet or
send a ping ack and then get an ICMP indicating the port got closed. The
server will then view this as a failure.
Fixes: 3136ef49a14c ("rxrpc: Delay terminal ACK transmission on a client call")
