platform/x86/intel: Fix pmt_crashlog array reference
The probe function pmt_crashlog_probe() may incorrectly reference
the 'priv->entry array' as it uses 'i' to reference the array instead
of 'priv->num_entries' as it should. This is similar to the problem
that was addressed in pmt_telemetry_probe via commit 2cdfa0c20d58
("platform/x86/intel: Fix 'rmmod pmt_telemetry' panic").
