LU-17356 quota: fix qmt_pool_new_conn

LU-17356 quota: fix qmt_pool_new_conn

Wrong argument passed into qmt_dom from
qmt_pool_new_conn caused a panic:

  qmt_sarr_get_idx()) ASSERTION( arr_idx <
    qpi->qpi_sarr.osts.op_count && arr_idx >= 0 )
    failed: idx invalid 0 op_count 0

Add conf-sanity_33d that reproduces above
assertion without the fix.
