David Howells cf6b97e183 rxrpc: Fix response to PING RESPONSE ACKs to a dead call ...

[ Upstream commit 6f769f22822aa4124b556339781b04d810f0e038 ]

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: 18bfeba50d ("rxrpc: Perform terminal call ACK/ABORT retransmission from conn processor")
