Bug Description
cinder config:
rbd_
Typical scenario:
1.create a raw volume C1
2.create volume C2 from C1 (clone depth is 1)
3.create volume C3 from C2 (clone depth is 2)
4.create snapshot S3 for volume C3
5.create volume C4 from S3 (clone depth is 3, but we don't flatten volume from snapshot here)
then the clone depth will grow unlimited.
Analysis;
1.we ignore to check clone depth when create volume from snapshot
