nat_cnt[] is updated while callers hold nat_tree_lock, but F2FS samples
the counters locklessly in f2fs_available_free_memory(),
excess_dirty_nats(), and excess_cached_nats(). Those helpers only steer
cache reclaim and background sync heuristics; they do not control NAT
entry lifetime or checkpoint correctness.
Document the intent with data_race(READ_ONCE()) and a short comment
instead of adding locking to the balance path.
