Testcase to reproduce this bug:
1. mkfs.f2fs -O extra_attr -O inode_crtime /dev/sdd
2. mount -t f2fs /dev/sdd /mnt/f2fs
3. touch /mnt/f2fs/file
4. xfs_io -f /mnt/f2fs/file -c "fsync"
5. godown /mnt/f2fs
6. umount /mnt/f2fs
7. mount -t f2fs /dev/sdd /mnt/f2fs
8. xfs_io -f /mnt/f2fs/file -c "statx -r"
stat.btime.tv_sec = 0
stat.btime.tv_nsec = 0
This patch fixes to recover inode creation time fields during
mount.
