How about one specify (managed='no|yes') for scsi hostdev?
"managed" is related to nodeDeviceDettach/nodeDeviceReAttach. For SCSI
device, we can't do this. If we do this, the /dev/sg* is no more visible.
As docs in 3/10: "user is responsible to make sure the device is not
used by host". "managed" is ignored by us.
