* Added an UninitializeMedia() method to KDiskDevice that also resets the

device geometry.
* If SetTo() reports no media, and GetGeometry() fails, the device geometry
  is now reset as well.
* KDiskDeviceManager::_ScanPartition() no longer unmarks the partition busy;
  this is now done by the caller, and done independently from the outcome of
  _ScanPartition(). This also fixes the problem that devices with no media
  were never marked unbusy (and thus were ignored subsequently).
