isdn: eicon: Use offsetof

Use offsetof instead of explicit implementation.

* fixes bug with omitted & like:
  len = (byte)(((T30_INFO *) 0)->station_id + 20)

* avoids compiler warnings with wrong sizes (pointer-to-char cast):
  len = (byte)(&(((T30_INFO *) 0)->universal_6));

* cleans up the code
