#421 TTI: tau_getTrnDirectory() compares different topographie counters

[Steffen Hieber]

tau_getTrnDirectory() compares trnTopoCnt with etbTopoCnt to detect changes, which is always true, because those are two different topographie counters.

    if (appHandle->pTTDB->trnDir.cstCnt == 0 ||
        appHandle->pTTDB->trnDir.trnTopoCnt != appHandle->etbTopoCnt)     /* need update? */
    {
        ttiRequestTTDBdata(appHandle, TTDB_TRN_DIR_REQ_COMID, NULL);
        return TRDP_NODATA_ERR;
    }
