ipcpd: Close dt stat_used race vs rib readdir
The stat_used function updated dt.stat[fd].stamp under the per-stat
mutex, released it, then took dt.lock wrlock to bump dt.n_flows. A
concurrent dt_rib_readdir holding dt.lock rdlock between those two
critical sections saw the new stamp but the old n_flows.
