fix fallout from: 'stats: new trackers for lchan life duration'

In lchan_fsm_cleanup(), ensure that the time_cc timer is actually inactive
before deallocating. Do so via lchan_reset(), to also make sure the
timer is stopped in all other situations where the lchan is deactivated.

This fixes an infinite-loop deadlock as described in OS#5554:
- run BSC_Tests.TC_chan_act_ack_est_ind_noreply
- restart the BTS process after the test is done
- osmo-bsc enters infinite loop in osmo_timer_del()

The reason is that lchan_fsm_cleanup() fails to stop a running active_cc
timer upon lchan deallocation. TC_chan_act_ack_est_ind_noreply
incidentally terminates OML while the timer is still active.
