prepare dyn TS: act lchan: fetch the channel mode a bit later

Dyn TS will add a new type of chan activation, which does not need a Channel
Mode IE. Incidentally, the dyn PDCH also doesn't need this IE if it opts for
sending a PDCH ACT instead. So it makes sense to compose the Channel Mode IE
only after the dynamic decisions are done.
