Restore from NAS backup is not failing for VM with template / disks < 1 GB, fails with "Root disk size should be a positive number." error.

The size computation below, returns 0 for disks < 1 GB.

   @sureshanaparti I have tried to reproduce the issue with the same steps. I could restore a VM from the backup and also could create a new VM. May this is fixed already. Could you please check and reopen the issue if there is something else needs fixing.
