commit 6d13f62d931ba638e54ba56f3a7dd3080ffb485a upstream.

skl_probe() releases a runtime pm ref unconditionally wheras
skl_remove() acquires one only if the device is wakeup capable.
Thus if the device is not wakeup capable, unloading and reloading
the module will result in the refcount being decreased below 0.
Fix it.
