stp: Use SI in valid range when transmitting data

ITU Q.704 14.2.1 defines Service Indicator as being 4 bits, hence valid range of the field is 0..0x0F. M3UA encodes it inside a full octet "justified to the least significant bit. Unused bits are coded `0'."

Make sure we send a value inside range, since newer libosmo-sigtran will validate the received m3ua field. Use SI=0010 "spare" since we are not really sending any meaningful data.
