Couple of things happening in this patch:
1) We can mark the device we're adding onto active list as used
way before - when adding it onto temporary list.
2) When actually moving device from a temporary helper list onto
the list of active devices we check if the device isn't
already there. The same check is performed by
virSCSIVHostDeviceListAdd() later. Drop this duplicity.
3) The 'error' label is renamed to 'rollback' to reflect what it
is actually doing. While in the rest of the code we don't
allow random label names, this source file is different.

Note that I've rebuilt this on a machine with a more modern kernel and
