rxrpc: Adjust the rxrpc_rtt_rx tracepoint

Browse Source 
Adjust the rxrpc_rtt_rx tracepoint in the following ways:

 (1) Display the collected RTT sample in the rxrpc_rtt_rx trace.

 (2) Move the division of srtt by 8 to the TP_printk() rather doing it
     before invoking the trace point.

 (3) Display the min_rtt value.
