    hotplug: Do not run auto span configuration if spans are auto assigned.
    
    This reapplies the change made in commit (6ed0adc08 "dahdi_span_config: Do not run auto
    span configuration if spans are auto assigned.") which appears to have been
    accidentally removed in (7f826a7d35 "hotplug modularization: split logic to
    scriptlets").
    
    To rationale from commit 6ed0adc08:
    
    I have seen cases were users run:
    
      # modprobe <driver>; dahdi_cfg -c <custom config file>
    
    and the spans end up misconfigured because dahdi_span_assignments ends up
    running, via udev, after the user configured the span the way it wanted.
    
    dahdi_span_assignments now looks at auto_assign_spans module parameter on
    dahdi.ko, like dahdi_handle_device already does, to determine if legacy or udev
    based configuration is being done.
