[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. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
