ensure pm_runtime_put() is called, on pm_runtime_get_sync()
failure.
Without this, after a failed call, the runtime PM usecount will have
been incremented, but not decremented causing the usecount to never
reach zero after a failure. Thanks to Kevin for educating about it.
While at it also fix a missing pm_runtime_disable in the probe error
path.
