In a multiple error scenario, we may end up with a "frozen" Primary, that has no access to any data (no local disk, no replication link). If we then resume-io, we try to generate a new data generation id, which will fail if there is no longer a local disk. Double check for available local data, which prevents the NULL pointer deref. If we are diskless, turn the resume-io in this situation into the first stage of a "force down", by bumping the "effective" data gen id, which will prevent later attach or connect to the former data set without first being demoted (deconfigured).
