xpp: Don't deactivate XPDs on unregistration

* A bug was introduced during migration to dahdi_device code:
    http://svnview.digium.com/svn/dahdi?view=rev&rev=10273
* Marking XPDs as non-functional (card_present=0, XPD_STATE_NOHW)
  was moved from xbus_request_removal() into xpd_dahdi_preunregister()
* As a result, unregistering an Astribank, made it non-functional
  so trying to re-register it later caused errors (e.g: "Cannot open"
  error message from xpp_open())
* This fix move XPD deactivation into the proper location (during
  xbus_deactivate()
