dm cache: set needs_check flag after aborting metadata

Browse Source 
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).
