rbd: default nouuid if the formattype is xfs

The problem happens when multiple PVCs with the
same UUID are attached/mounted on a node. This
can happen after creating a PVC from a snapshot,
or cloning a PVC.

make nouuid as the default mount option if
the format type is xfs to avoid mounting
issues.
