Btrfs: fix missing check before creating a qgroup relation
Step to reproduce:
mkfs.btrfs <disk>
mount <disk> <mnt>
btrfs quota enable <mnt>
btrfs qgroup assign 0/1 1/1 <mnt>
umount <mnt>
btrfs-debug-tree <disk> | grep QGROUP
If we want to add a qgroup relation, we should gurantee that
'src' and 'dst' exist, otherwise, such qgroup relation should
not be allowed to create.
