Store "Channel rate and type" from RSL Channel Mode IE in BTS

The RSL "Channel rate and type" field from the RSL Channel Mode IE
in RSL_CHAN_ACTIV and RSL_MODE_MODIFY_REQ messages is the only place
where the BSC differentiates between a normal TCH and the special
TCH modes used in VGCS or VBS.  Let's copy this field from the RSL
message into the lchan state, so that BTS models can actually (in
subsequent patches) reflect it when activating the L1.
