xen/balloon: fix balloon kthread freezing
Commit 8480ed9c2bbd56 ("xen/balloon: use a kernel thread instead a workqueue") switched the Xen balloon driver to use a kernel thread. Unfortunately the patch omitted to call try_to_freeze() or to use wait_event_freezable_timeout(), causing a system suspend to fail.
