LU-11768 test: make at_max to take effect

In test_6 of sanity-quota, the "at_max" won't affect
the "at_current" if there is no RPC to be sent in that
import, which still makes the following DQACQ request
to have larger timeout value and triggers watchdog.

Fixes: d8226b93 ("LU-11768 test: limit at_max to timeout in time")
Test-Parameters: trivial \
testlist=sanity-quota,sanity-quota,sanity-quota,sanity-quota,sanity-quota
