When the method del_lchan is called, closed_channel_nr still contains a dict that contains the channel number under the key 'logical_channel_number'. This will lead to an exception. We must extact the channel number from the dict before we can use it with del_lchan. (See also created_channel_nr) Related: OS#6094 Change-Id: I399856bc227f17b66cdb4158a69a35d50ba222a7
