[PATCH] osmocom-bb[fixeria/trx]: trxcon: clean up DATA / TRAFFIC confirmation API

[Vadim Yanitskiy]

Review at  https://gerrit.osmocom.org/7211

trxcon: clean up DATA / TRAFFIC confirmation API

  - change 'l1ctl_tx_data_conf' symbol to 'l1ctl_tx_dt_conf' in
    order to indicate that it's used for both DATA and TRAFFIC;

  - introduce a 'traffic' flag, which is used to define either
    TRAFFIC or DATA confirmation type;
