Move not provisioned nodes to error status

When there are lot of nodes to provision and we provision
them by chunks, we could fail in the middle due to "Too many
nodes failed to provision". If so, we need to append those
nodes where we did not started provision at all to the list
of failed nodes. Otherwise, those nodes will be reported
as 'provisioned' with progress = 100 and rebooted.
But for some reasons we bind all nodes before starting provision
to debian-installer profile in cobbler, and being rebooted
these not provisioned nodes will fail to boot, because since
7.0 we put empty files where cobbler expects debian-installer
kernel and initrd files. :-)
