kernel - Auto-initiate message stream for udev on read()

* Ensure the device is initiated when read() is issued for /dev/udev,
  otherwise no events will be queued.

  This allows a simple cat /dev/udev to return the XML stream without
  having to issue any ioctls.

* Reorder the devfs scan and initiation to close a race where an event could
  be lost.
