sysctl: define upper limit for sched_freq_reporting_policy
Setting sched_freq_reporting_policy tunable to an unsupported
values results in a warning from the scheduler. The previous
policy setting is also lost.
As sched_freq_reporting_policy can not be set to an incorrect
value now, remove the WARN_ON_ONCE from the scheduler.
