mm/balloon_compaction: suppress allocation warnings

There is no reason to print warnings when balloon page allocation fails, as they are expected and can be handled gracefully. Since VMware balloon now uses balloon-compaction infrastructure, and suppressed these warnings before, it is also beneficial to suppress these warnings to keep the same behavior that the balloon had before.
