Convert lchan CCCH_LCHAN to chan_nr BCCH and viceversa
Before this patch it was being coded as SDCCH4 TS0 SS 0, and as a
result the state LCHAN_REL_ACT_OML applied in opstart_compl in abused
SDCCH4 TS0 SS 4 was not being checked when deciding whether to send a
Chan Act ACK in rsl_tx_chan_act_acknack.
