trans_free: safeguard against a still running CC timer on free
Make sure to deactivate trans.cc.timer when freeing a CC transaction.
Log an error if should be necessary.
This prevents a segfault when we receive a BSSMAP Clear Request from BSC during
an ongoing CC operation. The BSSMAP Clear Request currently triggers immediate
freeing of the conn, while we should still do a graceful release first. While
this patch does not fix the underlying error, it does prevent the MSC from
crashing due to a stale timer, whatever the cause might be.
