trxcon/l1ctl.c: fix: handle ARFCN from L1CTL_DM_EST_REQ
A BSC may allocate a dedicated channel on any ARFCN, not necessary on the same one where a mobile station has requested this channel. For some reason, the ARFCN info of L1CTL_DM_EST_REQ message was not handled by trxcon. Let's fix this. Related: OS#3526 Change-Id: I16ed5c64236c159bfa39002b05094c1f6c171f6b
