    rxrpc: rxperf: Fix uninitialised variable
    
    Dan Carpenter sayeth[1]:
    
    The patch 75bfdbf2fca3: "rxrpc: Implement an in-kernel rxperf server
    for testing purposes" from Nov 3, 2022, leads to the following Smatch
    static checker warning:
    
            net/rxrpc/rxperf.c:337 rxperf_deliver_to_call()
            error: uninitialized symbol 'ret'.
    
    Fix this by initialising ret to 0.  The value is only used for tracing
    purposes in the rxperf server.
