[PATCH 2/2] cpufreq/amd-pstate-ut: Don't fail boost test case if CPB isn't supported

[Mario Limonciello <mario.limonciello@amd.com>]

cpudata->boost_supported will only be configured when a CPU actually
supports core performance boost. Add an extra guard into the check
to ensure it only runs when CPB is present.
