network: update comment and log message
After 4b30f2e135ee84041bb597edca7225858f4ef4fb, reading stable_secret sysctl property fails with -ENOMEM, instead of -EIO. This is due to read_full_virtual_file() uses read() as the backend while read_one_line_file() uses fgetc(). And each functions return different error on fails. Anyway, the failure is harmless here. So, the log message and comment is updated. Closes one of the issues in #19410. (cherry picked from commit 0e27527170aa0179f2a4b3b55b78ddc049f815b9) (cherry picked from commit 2417e9b59aa654e4b3def3399576ebbc2cdd7c95)
