xpp: dahdi_registration: force re-assignment

* The system state causing the bug:
  - DAHDI has auto_assign_spans==1
  - No /etc/dahdi/assigned-spans.conf

* The bug scenario:
  - During initial device detection, they are assigned by
    DAHDI driver.
  - Later we run "dahdi_span_assignment remove"
  - Then, a "dahdi_registration on" would not assign any span.

* The fix:
  - Using the '-R' option, force "dahdi_registration on" to also
    do "dahdi_span_assignment auto" on relevant devices.
  - This is the way it's called by /usr/share/dahdi/dahdi_auto_assign_compat
