    Relax virtio requirement in config file
    
    When the virtio transport was introduced the schema was changed to
    require a <virtio> transport in vhostmd.conf. When updating existing
    deployments without a virtio transport specified in vhostmd.conf,
    vhostmd fails to start
    
    /usr/sbin/vhostmd -d
    /etc/vhostmd/vhostmd.conf:41: element globals: validity error : Element
    globals content does not follow the DTD, expecting (disk , virtio ,
    update_period , path , transport+), got (disk update_period path transport )
    validate_config_file(): Failed to validate :/etc/vhostmd/vhostmd.conf
    Config file: /etc/vhostmd/vhostmd.conf, fails DTD validation
    
    Relax the requirement for virtio transport in the schema. With the
    introduction of multiple transports perhaps the others shoud be optional
    as well, but requiring virtio is clearly a regression.
