bdevperf: prevent multiple performance statistics poller registering 



Current implementation allows to run bdevperf with --wait-for-rpc and
without -z option. As the result several statistics pollers will be
registered. Let's add guardian to prevent this.
In the case of multiple test running guardian also will be helpful.
