peci: cpu: Fix use-after-free in adev_release()

When auxiliary_device_add() returns an error, auxiliary_device_uninit()
is called, which causes refcount for device to be decremented and
.release callback will be triggered.

Because adev_release() re-calls auxiliary_device_uninit(), it will cause
use-after-free:

[ 1269.464007] refcount_t: underflow; use-after-free.
