Unable to access to a mount point after denying an access to a share during writing action

Description of problem:
After denying an access to a share during writing action.
On CephFS-NFS Ganesha we get "stale file handle" when trying
to ls to the mount point, however, on Netapp and CephFS-Native
we get "Permission denied".
So that we can access to the mounted directory we have to unmount
and remount again.

Steps to Reproduce:
1. Launch an instance
2. Create a share
3. Grant RW access to the share
4. Perform ssh to instance
5. Mount the share
6. Writing to the share and during the writing operation changing the access level to "ro".
7. Perform ls to the mount point.

Actual results:
Unable to access to the mount point.
"ls: cannot access '/mnt': Stale file handle"

Expected results:
We should be able to access to the mount point and see that there is a file.
