vzdump: log 100% percent in case $target is 0

When $target is 0, that means we don't have to upload any data, in which
case we're immediately done.

Otherwise incremental backups with no changes display a really weird
  status: 0% (0.0 B of 0.0 B), duration 0, read: 0 B/s, write: 0 B/s
when they're actually done already.
