Dashboard: NFS export edit operation removes CephFS subvolume group and subvolume association

[andreus94]

When editing an NFS export from the Ceph dashboard, the CephFS subvolume group and subvolume associations are lost.

The export continues to work, but after saving it points to the parent path instead of the configured subvolume.

Environment
Ceph release: Tentacle 20.2.1
Deployment: cephadm
Backend: CephFS
Protocol: NFS-Ganesha
Steps to reproduce
Create a CephFS subvolume group and subvolume
Create an NFS export from the dashboard
Edit the export from the dashboard
Save the configuration
Expected behavior

The export should keep:

subvolume group
subvolume
Actual behavior

After saving:
subvolume group and subvolume associations are lost
the export points to the parent path
Workaround

Manually reselect the subvolume group and subvolume before saving.
