dev_set_name() in macio_add_one_device() allocates memory for name,
it need be freed when of_device_register() fails, call put_device()
to give up the reference that hold in device_initialize(), so that
it can be freed in kobject_cleanup() when the refcount hit to 0.
macio device is freed in macio_release_dev(), so the kfree() can be
removed.
