Steps to reproduce:
# mkfs.btrfs -f /dev/sda8
# mount /dev/sda8 /mnt
# mkdir /mnt/subvolumes
# btrfs sub create /mnt/subvolumes/subv1
# btrfs sub create /mnt/subvolumes/subv1/subv1.1
# btrfs sub list -o /mnt/subvolumes/subv1 <----we did not list anything
The problem is that we don't set @top_id right, fix it.
