perf tools: Remove a pointless check

Static analyser cppcheck says:

  linux-6.16/tools/perf/util/tool_pmu.c:242:15: warning:
      Opposite inner 'if' condition leads to a dead code block. [oppositeInnerCondition]

Source code is:

        for (thread = 0; thread < nthreads; thread++) {
            if (thread >= nthreads)
                break;
