xen/balloon: fix balloon kthread freezing
commit 96f5bd03e1be606987644b71899ea56a8d05f825 upstream.
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.
Fixes: 8480ed9c2bbd56 ("xen/balloon: use a kernel thread instead a workqueue")
