Why shouldn't we change the value of LATENCY_MULTIPLIER for old
governors as well? They use the same calculations and the sampling
rate there is also this bad (like rate_limit_us).

If we aren't going to change that for old governors, then we can
create a local version of LATENCY_MULTIPLIER for schedutil I believe.
