Konstantin Khlebnikov dbb9e9ff78 mm/balloon_compaction: fix deflation when compaction is disabled ...

commit 4d88e6f7d5 upstream.

If CONFIG_BALLOON_COMPACTION=n balloon_page_insert() does not link pages
with balloon and doesn't set PagePrivate flag, as a result
balloon_page_dequeue() cannot get any pages because it thinks that all
of them are isolated.  Without balloon compaction nobody can isolate
ballooned pages.  It's safe to remove this check.

Fixes: d6d86c0a7f ("mm/balloon_compaction: redesign ballooned pages management").
