MFC r308437 and r308461:
Range check the jitter values to avoid bogus sample rate adjustments.
The expected deviation should not be more than 1Hz per second. The USB
v2.0 specification also mandates this requirement. Refer to chapter
5.12.4.2 about feedback.

Allow higher sample rates to have more jitter than lower ones.
