osmo-bts-trx: shut down on stale clock indication from transceiver

We expect the transceiver to be a reliable, monotonic clock source.
If it reports an FN far behind our local timer (elapsed_fn < 0) while
far more wall-clock time elapsed than its FN advance accounts for,
its clock has likely stalled and the indication carries a stale frame
number.  Acting on it drags the scheduler backwards and re-transmits
already-sent TDMA frames, corrupting lchan-internal state(s).

Detect this and shut down the process, same rationale as the existing
"PC clock skew too high" check in trx_fn_timer_cb().
