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.
