Revert "lapdm: Append RSL_IE_OSMO_ABS_FRAME_NUMBER to RSLms msgs towards upper layers"
This reverts commit d981794113efef3cc1195cde82043c5c66937b11.
osmo-bts is forwarding the msgbs as they come from lapdm to the RSL on
the wire, which means we end up sending the osmocom-specific IEs on the
wire, something which was not envisioned when adding this IE.
