Make query to quota usage table order preserved

Currently, the query to quota usage table is not order
preserved. This might cause deadlock in large-scale
deployment: different calls may lock rows in different
order, and deadlock will happen.

This patch adds order_by to the query and make the query
to the table order preserved.
