File Quota attributes not getting inherited to the cloned volume

Version-Release number of selected component (if applicable):
ceph version 16.2.0-146.el8cp (56f5e9cfe88a08b6899327eca5166ca1c4a392aa) pacific (stable)

How reproducible:

Steps to Reproduce:
1.Create a subvolume and mount it on directory using kernel mount
2.Setfattr to the mounted directory both file and byte quotas
3.create snapshot
4.create a clone of the subvolume
5.mount the cloned volume using fusemount
6.check the quota attributes of the mounted directory

Actual results:
bytes quota is getting inherited where as file quota not getting inherited

Expected results:
both the quotas should get inherited
