objstore: allow vdev allocation with import-only backends
Some backends will not be able to create new vdevs - only import existing
ones. Those backends still need a struct objstore_vdev. Therefore, we must
allow the vdev structure allocation to succeed even if the backend
definition doesn't contain a create_vdev op.
