PM / devfreq: Fix leak in devfreq_dev_release()
commit 5693d077595de721f9ddbf9d37f40e5409707dfe upstream.
srcu_init_notifier_head() allocates resources that need to be released
with a srcu_cleanup_notifier_head() call.
Reported by kmemleak.
Fixes: 0fe3a66410a3 ("PM / devfreq: Add new DEVFREQ_TRANSITION_NOTIFIER notifier")
