-stable review patch. If anyone has any objections, please let us know.

From: Marcelo Tosatti <[email protected]>
upstream commit: 84a139a985300901dfad99bd93c7345d180af860
Break out of wait_event_interruptible() if freezing has been requested,
in the vballoon thread. Without this change vballoon refuses to stop and
the system can't suspend.
