LU-9158 quota: adjust quota ASAP

In qsd_upd_thread, the quota adjust request will only be
scheduled to run when the current time (seconds) is larger
than the queued time (seconds). The transactions in subtest 12b
of sanity_quota are committed in one second simultaneously,
which cause the quota is not freed.
