Update locking notes on several fields to reflect locking already in the tree: - td_standin is (k + a) as it is only touched by either curthread or when   a thread is being created. - td_upcall is (k + j) - td_sticks is (k) rather than the earlier (j) note. - td_uuticks and td_usticks are both (k). - td_intrval is (j) - Neither kg_nextupcall or kg_upquantum seem to be locked and that seems   to be on purpose, so mark those as (n).
