Bug#666788: partman no longer prints warning when no disk

[Martin Michlmayr <tbm@cyrius.com>]

Package: partman-base
Version: 153
Severity: important

I booted d-i without any disks and got the following screen.  I'm
pretty sure partman used to print a proper warning/error if there
are no disks.

  ┌────────────────────────┤ [!!] Partition disks ├─────────────────────────┐
