[PATCH installer] install: fix progress percent reporting when creating root and swap

[Christoph Heiss <c.heiss@proxmox.com>]

Currently the progress reported when using the auto-installer (where it
is most noticeable) is:

  INFO: progress   0.0 % - cleanup root-disks
  INFO: progress   2.0 % - create partitions
  INFO: progress   3.0 % - create LVs
  INFO: progress   1.0 % - create swap space
  INFO: progress   1.1 % - creating root filesystems
  INFO: progress   5.0 % - creating root filesystem
  [..]

.. i.e. the progress can go backwards.

Fix it by aligning the two update_progress() calls with the others,
so that the progress is reported as originally intended:

  [..]
  INFO: progress   4.0 % - create swap space
  INFO: progress   4.5 % - creating root filesystems
  [..]
