register_models in db/sqlalchemy/models.py references non-existent ExportDevice

ExportDevice was removed by Vish during change: I1b1626f40bebe8466ab410fb174683293c7c474f (https://github.com/openstack/nova/commit/eb03d47fecd3bfc24243da29ee01679b334a08fe#nova/db/sqlalchemy/models.py)

This is still referenced in db/sqlalchemy/models.py:

def register_models():
    """Register Models and create metadata.

    Called from nova.db.sqlalchemy.__init__ as part of loading the driver,
    it will never need to be called explicitly elsewhere unless the
    connection is lost and needs to be reestablished.
    """
    from sqlalchemy import create_engine
    models = (Service, Instance, InstanceActions, InstanceTypes,
              Volume, ExportDevice, IscsiTarget, FixedIp, FloatingIp,
              Network, SecurityGroup, SecurityGroupIngressRule,
              SecurityGroupInstanceAssociation, AuthToken, User,
              Project, Certificate, ConsolePool, Console, Zone,
              VolumeMetadata, VolumeTypes, VolumeTypeExtraSpecs,
              AgentBuild, InstanceMetadata, InstanceTypeExtraSpecs, Migration,
              VirtualStorageArray, SMFlavors, SMBackendConf, SMVolume,
              InstanceFault, Aggregate, AggregateMetadata)
    engine = create_engine(FLAGS.sql_connection, echo=False)
    for model in models:
        model.metadata.create_all(engine)

This looks like an accidental omission to me, unless I am missing something.
