lib: Set a timeout on FRCT control packets
Time out frct_tx for control packets at 250us so a full tx ring cannot
stall the timer wheel (and with it KA, TLP, RXM fires). DATA frames
(fresh, RXM, TLP, FIN) keep blocking - dropping them would lose
recovery progress.
Add inact_drop, drf_rebase, rq_released, tlp_snd, sdu_snd_alloc,
sdu_snd_tx, sdu_sole, rxm_tx_dead, and per-type tx_drop counters.
