systemd-udev更新设备分区符号链接失败报错

【环境信息】
OS版本及分支信息
系统：openEuler 20.03 LTS SP4
软件包版本：systemd-243-79

【问题复现步骤】
1.添加一个新的磁盘
2.使用下面的命令，对新磁盘进行分区(/dev/sdb)

```
parted -s /dev/sdb mklabel gpt
j=0
for i in `seq 1 30`; do
    ((j=$((j + 3))))
    ((k=$((j - 3))))
    parted -s -a optimal /dev/sdb mkpart primary $k% $j%
done
```

3.在创建分区过程中，udev的cpu占用率高，message日志有报错信息：
