net: core: protect rate estimator statistics pointer with lock
Extend gen_new_estimator() to also take stats_lock when re-assigning rate
estimator statistics pointer. (to be used by unlocked actions)
Rename 'stats_lock' to 'lock' and change argument description to explain
that it is now also used for control path.
