deadcode warnings in perf/ipsec_perf.c

[ColinIanKing]

Again, maybe intentional or a false positive, but I'm seeing static analysis warnings in perf/ipsec_perf.c

2381                for (arch = 0; arch < NUM_ARCHS; arch++) {
2382                        if (archs[arch] == 0)
2383                                continue;
2384

seems that case 3: can be removed in this switch
