During a Mobile Originating voice call, we would normally start receiving traffic indications with ringback tone (or even some melody) before the call gets CONNECTed. So in order for the user to be able to hear that, we need to init the voice call handler earlier (on receipt of CC ALERTING message). We should not be transmitting voice/data frames before the call gets CONNECTed, so add 'rx_only' flag to the TCH state. In tch_send_msg() drop msgb if this flag is set. Rx only mode makes no sense for data calls, so in tch_recv_cb() we discard received DL frames and thus do not trigger sending UL frames.
