ceph-volume: set default value for BlueStore.block_lv to None

This change updates the `BlueStore` class in
`ceph_volume.objectstore` by initializing the `block_lv` attribute
to `None` with the type `Optional[Volume]`. This ensures that the
attribute has a default value and avoids potential runtime errors
when the attribute is accessed before being explicitly assigned.
