ESP32-C3，ESP-IDF版本4.3.2
使用I2C驱动OLED（驱动芯片SSD1306），开机正常驱动显示，持续刷新屏幕，运行一段时间后，总是会出现如下错误：
(1629509) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time:
(1629509) task_wdt: - IDLE (CPU 0)
(1629509) task_wdt: Tasks currently running:
(1629509) task_wdt: CPU 0: esp_timer
添加LOG跟踪发现，出问题前，软件运行到components\driver\i2c.c的第1238行i2c_hw_fsm_reset(i2c_num);返回后，就没有退出while，也没有退出当前函数i2c_master_cmd_begin，软件持续打印如上的喂狗失败的的LOG。

配置menuconfig使能task watchdog超时触发异常重启，dump数据内容如下：
