    Use correct hostname to get instances.

    socket.getfqdn() would return a fully qualified domain name
    which maybe invalid for nova to get instances by hostname.
    If the host that runs devstack is virtual(like running
    devstack on AWS), socket.getfqdn() may return a domain name
    which is not the host name and nova cannot use that to get
    instances running on current host.

    Fix bug: #1166717
