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"). Cc: "David E.
