Yongqiang Liu 8fb4c98f20 cpufreq: Init completion before kobject_init_and_add() 
commit 5c51054896 upstream.

In cpufreq_policy_alloc(), it will call uninitialed completion in
cpufreq_sysfs_release() when kobject_init_and_add() fails. And
that will cause a crash such as the following page fault in complete:

BUG: unable to handle page fault for address: fffffffffffffff8
