Avoid a race between /etc/init.d/dahdi and hotplug scripts:

* On some systems/configurations, dahdi init script may kick in
  during the time that hotplug scripts are configuring spans.

* It may lead to a race since the init script runs "dahdi_auto_assign_compat"
  which calls "dahdi_registration" and that tries to run
  "dahdi_span_assignments auto ..."

* Use the newly-added "dahdi_span_assignments" "unmatched" operation.

* Now the "dahdi_auto_assign_compat" script only runs "dahdi_registration"
  if there are no "unmatched" Astribanks.

* This prevents the race in fully configured systems.
  The race may still exist on partially-configured systems.
