Yang Yingliang da36a2a76b xen/pcpu: fix possible memory leak in register_pcpu()
In device_add(), dev_set_name() is called to allocate name, if it returns
error, the 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().

Fixes: f65c9bb3fb72 ("xen/pcpu: Xen physical cpus online/offline sys interface")
