logger: Filesystem backend doesn't work except for first time boot

Describe the bug After activating LOG_BACKEND_FS, CONFIG_FILE_SYSTEM_LITTLEFS and their dependencies, it worked as expected on the very first time boot (clean storage partition).

The problem is after rebooting the board, nothing new got saved to the log file created from the first time boot nor a new file created. as if logging to filesystem is completely stopped.

What have you tried to diagnose or workaround this issue?

I tried to do some debugging, and I found that adding fs_seek(&file, 0, FS_SEEK_END); just before https://github.com/zephyrproject-rtos/zephyr/blob/882600834e80d2d3d5db4e61d72f63a8bd997fcc/subsys/logging/log_backend_fs.c#L177 make things work. but I think this is not the right way to do it.

After adding the workaround above, makes the logging backend create a new file on each reboot, instead of appending to the old one till it reaches the CONFIG_LOG_BACKEND_FS_FILE_SIZE. that also breaks the limit CONFIG_LOG_BACKEND_FS_FILES_LIMIT, I end up getting 3 files after 3 or more reboots

log.0000
log.000x
log.000(x+1)

To Reproduce Steps to reproduce the behavior:

replace the content of zephyr\samples\hello_world\src\main.c with the following sample code:

#include <zephyr.h>
#include <sys/printk.h>

#include <logging/log.h>
LOG_MODULE_REGISTER(main, LOG_LEVEL_DBG);

  void main(void)
  {
      int x = 0;
      while (x < 20)
      {
          k_sleep(K_MSEC(200));
          LOG_INF("Hello World! %s %d", CONFIG_BOARD, x++);
      }
  }

west build -b stm32f769i_disco ./samples/hello_world
west build -b stm32f769i_disco -t menuconfig and use the attached .config below
