rxrpc: Fix response to PING RESPONSE ACKs to a dead call
Stop rxrpc from sending a DUP ACK in response to a PING RESPONSE ACK on a
dead call. We may have initiated the ping but the call may have beaten the
response to completion.
Fixes: 18bfeba50dfd ("rxrpc: Perform terminal call ACK/ABORT retransmission from conn processor")
