This info can be useful to filter devices visible
to mgmt clients so that they won't see devices that
unsafe/not meaningful to pass thru.
Provide class info the way it is provided by udev or
kernel that is as single 6-digit hexadecimal.
Class element is not optional. I guess this should not
break users that use virNodeDeviceCreateXML because
they probably specify only scsi_host capability on
input and then node device driver gets other capabilities
from udev after device appeared.
HAL driver does not get support for the new element in
this patch.
