l1sap: if lchan is in loopback, don't accept incoming RTP
When the lchan is in loopback mode, we loop back all uplink blocks into
downlink blocks. We do not processs any RTP frames for that lchan
anymore. Rather, we discard those RTP frames to avoid mixing
looped-back samples with those received from remote.
