Other bts models like sysmo,lc15,oc2g properly handled
rel_act_kind=LCHAN_REL_ACT_REACT under the bts_model_lchan_deactivate()
implementation, but bts-trx didn't.
As a result, when BCCH_INFO(SYSINFO_TYPE_3) coming from BSC (RSL)
containing a different BS_AG_BLKS_RES triggers CCCH re-activation,
it would only deactivate it but not re-activate it.
That means no SIs were being scheduled if bts was configured with
"channel-descrption bs-ag-blks-res 2" in osmo-bsc.cfg, and phones would
not see the cell.
