Nadav Amit 468e0ffac8 vmw_balloon: Fix offline page marking with compaction 
The compaction code already marks pages as offline when it enqueues
pages in the ballooned page list, and removes the mapping when the pages
are removed from the list. VMware balloon also updates the flags,
instead of letting the balloon-compaction logic handle it, which causes
the assertion VM_BUG_ON_PAGE(!PageOffline(page)) to fire, when
__ClearPageOffline is called the second time. This causes the following
crash.

Fix it by updating the PageOffline indication only when a 2MB page is
enqueued and dequeued. The 4KB pages will be handled correctly by the
balloon compaction logic.
