platform/x86/intel/pmt: Fix kobject memory leak on init failure

When kobject_init_and_add() fails in pmt_features_discovery(), the
function returns without calling kobject_put(). This violates the
kobject API contract where kobject_put() must be called even on
initialization failure to properly release allocated resources.
