rxrpc: Generate extra pings for RTT during heavy-receive call
When doing a call that has a single transmitted data packet and a massive
amount of received data packets, we only ping for one RTT sample, which
means we don't get a good reading on it.
Fix this by converting occasional IDLE ACKs into PING ACKs to elicit a
response.
