xf86AddBusDeviceToConfigure(): Store device in DevToConfig[i].pVideo

After fc3ab84d the pVideo field in DevToConfig[i] is no longer
initialized, so it's always NULL. This causes the duplicate finding
algorithm in the beginning of the function to not work anymore as it
is based on this field.

The symptom of this bug is that X -configure reports

    Number of created screens does not match number of detected devices.
      Configuration failed.
    Server terminated with error (2). Closing log file.

rather than producing a working config file.

This patch fixes that bug by initializing the field before calling
xf86PciConfigureNewDev().
