Subject: [PATCH] common: logging: backend: Close the file after exceeding the
 write limit

There's no point in keeping the file open after the write limit is exceeded. This allows the file to be committed to the disk shortly after it is closed and avoids redundantly checking whether or not the write limit is exceeded.
