    Make resize raise exception when no valid host found

    When resize operation starts, it will ask conductor to find a
    valid host and try to resize to that host. When there is no valid
    host can be found ,current code return directly without error
    notification, which will make upper layer code (e.g novaclient)
    thinks the execution is succesfully performed and report 'Finished'.
    But actually it isn't due to no valid host was found.
