siox: fix possible memory leak in siox_device_add()

In the Linux kernel, the following vulnerability has been resolved:

siox: fix possible memory leak in siox_device_add()

If device_register() returns error in siox_device_add(),
the name allocated by dev_set_name() need be freed. As
comment of device_register() says, it should use put_device()
to give up the reference in the error path. So fix this
by calling put_device(), then the name can be freed in
kobject_cleanup(), and sdevice is freed in siox_device_release(),
set it to null in error path.
