bkmonitorbeat采集CPU使用率当CPU热更新扩容核心持续报错

[abbhb]

操作系统信息：
Centos7 GNU/Linux
版本信息:
bkmonitorbeat 3.22.1392
问题描述：
当对机器扩CPU核心数且不用重启会导致bkmonitorbeat的CPU单核使用率持续无法顺利上报，

因为代码里遇到错误return err后并没有将最新的数据覆盖进lastCPUTimeSlice里，导致无法自动恢复，只能手动重启bkmonitorbeat

相关代码如下

func getCPUStatUsage(report *CpuReport) error {
	var err error
	perCPUTimes, err := cpu.Times(true)
	if err != nil {
		return err
	}
	// 比较两次获取的时间片的内容的长度,如果不对等直接退出
	lastCPUTimeSlice.Lock()
	defer lastCPUTimeSlice.Unlock()

	// 判断lastPerCPUTimes长度，增加重写避免init方法失效的情况
	if len(lastCPUTimeSlice.lastPerCPUTimes) <= 0 || len(perCPUTimes) != len(lastCPUTimeSlice.lastPerCPUTimes) {
		lastCPUTimeSlice.lastPerCPUTimes, err = cpu.Times(true)
		if err != nil {
			return err
		}
	}

	l1, l2 := len(perCPUTimes), len(lastCPUTimeSlice.lastPerCPUTimes)
	if l1 != l2 {
		err = fmt.Errorf("received two CPU counts %d != %d", l1, l2)
		return err
	}

	for index, value := range perCPUTimes {
		item := lastCPUTimeSlice.lastPerCPUTimes[index]
		tmp := calcTimeState(item, value)
		report.Stat = append(report.Stat, tmp)
	}

	cpuTimes, err := cpu.Times(false)
	if err != nil {
		return err
	}

	// 判断lastCPUTimes的长度，增加重写避免init方法失效的情况
	if len(lastCPUTimeSlice.lastCPUTimes) <= 0 {
		lastCPUTimeSlice.lastCPUTimes, err = cpu.Times(false)
		if err != nil {
			return err
		}
	}

	cpuTimeStat := cpuTimes[0]
	lastCpuTimeStat := lastCPUTimeSlice.lastCPUTimes[0]
	report.TotalStat = calcTimeState(lastCpuTimeStat, cpuTimeStat)

	// 将此次获取的timeState重新写入公共变量
	lastCPUTimeSlice.lastCPUTimes = cpuTimes
	lastCPUTimeSlice.lastPerCPUTimes = perCPUTimes

	// per usage
	report.Usage, err = cpu.Percent(0, true)
	if err != nil {
		return err
	}

	for i := range report.Usage {
		if report.Usage[i] < 0 || int(report.Usage[i]) > 100 {
			report.Usage[i] = 0.0
		}
	}
	// total usage
	total, err := cpu.Percent(0, false)
	if err != nil {
		return err
	}

	report.TotalUsage = total[0]
	if report.TotalUsage < 0 || report.TotalUsage > 100 {
		report.TotalUsage = 0.0
	}
	return nil
}

这个问题已经在 #595 #128 已经被修复过，直接更新版本即可
