In the event that devm_devfreq_add_device() fails the device's qos freq list is left referencing df->idle_freq and df->boost_freq. Attempting to initialize devfreq again after a probe deferral will then cause invalid memory accesses in dev_pm_qos_add_request().Fix this by dropping the requests in the error path.
