pm_runtime_put_autosuspend() and pm_runtime_put_sync_suspend()
will decrease the rumtime PM counter even when it returns an error.
Thus a pairing decrement is needed to prevent refcount leak.
Fix this by adding pm_runtime_resume_and_get() on error handling path.

Hey Hsin-Yi,
While I can review this patch, I don't have the authority to merge it
since it is outside the scope of my maintainership. Rob Herring,
Daniel Vetter or David Airlie would have to Ack this patch.

pm_runtime_get_sync() will increase the rumtime PM counter
even it returns an error. Thus a pairing decrement is needed
