From: Aaron Lewis <aaronlewis@xxxxxxxxxx>
Provide the actual vs. expected count in the PMU event filter test's
asserts instead of relying on pr_info() to provide the context, e.g. so
that all information needed to triage a failure is readily available even
if the environment in which the test is run captures only the assert
itself.
