[ 9299.893835] F2FS-fs (vdd): Allow to mount readonly mode only
mount: /mnt/f2fs: WARNING: source write-protected, mounted read-only.
root@qemu:/ ps -ef|grep f2fs
root          94       2  0 03:46 ?        00:00:00 [kworker/u17:0-f2fs_post_read_wq]

There will be no deletion in readonly image, let's skip starting
discard thread to save system resources.
