    unattended: Fix target dev name for floppy nodes
    
    The name used for the target dev in libvirt XML is only used for
    ordering purpose, and does not necessarily have to be consistent with
    how the dev node would be named on a linux box.
    
    Since http://libvirt.org/git/?p=libvirt.git;a=commit;h=5729746543c
    (libvirt 3.1.0), libvirt actually forbid using "fd0" for the floppy
    target dev name, and defining a domain with such a node returns an
    error:
    XML error: Unknown disk name 'fd0' and no address specified
    
    This breaks Windows 7 unattended installation.
