Juergen Gross 0bec1ceaf1 xen/balloon: fix cancelled balloon action 
commit 319933a80f upstream.

In case a ballooning action is cancelled the new kernel thread handling
the ballooning might end up in a busy loop.

Fix that by handling the cancelled action gracefully.

While at it introduce a short wait for the BP_WAIT case.
