[#LU-12969] make sure we reset quota limits for all test ID/users

It looks current sanity-quota.sh assumed TSTID/TSTID2 mapped with quota_usr/quota_2usr.
However, in a real testing envirment this might be not true, and in Oleg's testing enviroment,
trying to add a new test66 which did not set any limits before test, but hit disk quota failure:
