  Ensure that dahdi_scan correctly reports VPM presence.

  The wct4xxp driver (for the dual/quad span T1/E1 cards) and the wcte12xp
  driver (for the single span VoiceBus-based T1/E1 cards) did not properly
  update the 'devicetype' field reported by dahdi_scan when a VPM was found
  during the card startup process. As a result, dahdi_scan did not show that
  a VPM was present on the card, even if it was.
