Increase min_rate for NDRPDR tests
Latency measurements break for loads less than 9 kpps per direction.
Setting min_rate to 90 kpps prevents 10% latency trial from breaking.
90 kpps should be enough for any type of test.
When some test finds a lower value, this patch will make the fail
with a message saying the loss rate at minimal load is too high
(instead of a cryptic error from 10% measurement without this patch).
