[ Upstream commit c404af950d14b71bfbf574a752b6c29d726baaba ]
Since commit afd9690c72c3 ("[media] ov6650: convert to the control framework"), if an error occurs during initialization of a control handler, resources possibly allocated to the handler are not freed before device initialiaton is aborted. Fix it.
