[S390] qdio: call qdio_free also if qdio_shutdown fails
qdio_cleanup is a wrapper function that should call qdio_shutdown and
qdio_free. qdio_free was not called if an error occured in qdio_shutdown
resulting in a missing free of allocated resources.
Call qdio_free regardless of the return value of qdio_shutdown.
