From: Mike Snitzer <snitzer@xxxxxxxxxx>
commit 6b9973861cb2e96dcd0bb0f1baddc5c034207c5c upstream.
Otherwise the commit that will be aborted will be associated with the
metadata objects that will be torn down. Must write needs_check flag
to metadata with a reset block manager.
Found through code-inspection (and compared against dm-thin.c).
