drm/msm/gpu: Drop qos request if devm_devfreq_add_device() fails
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.
