Description of problem:
Creating a new PVC from the snapshot of a RBD RWX block volume mode PVC fails because the volume mode of new PVC is set to Filesystem in UI. The volume mode is default to Filesystem and cannot be edited. Restore will fail because RWX access mode is not supported on rbd filesystem type volumes.

Error :
failed to provision volume with StorageClass "ocs-storagecluster-ceph-rbd": rpc error: code = InvalidArgument desc = multi node access modes are only supported on rbd `block` type volumes

Version-Release number of selected component (if applicable):
Cluster version is 4.6.0-0.nightly-2020-08-18-165040

How reproducible:

Steps to Reproduce:
1. Create an rbd PVC with access mode RWX in UI. Volume mode will be set to Block.
2. Create a snapshot of the volume.
3. Try to restore from the created snapshot.

Actual results:
New PVC creation from snapshot fails because volume mode is set to Filesystem which is not a supported configuration for rbx rwx PVC.

Expected results:
Volume mode should be set to the same value as in the parent PVC.
