dm cache: fix writethrough mode quiescing in cache_map

commit 131cd131a9ff63d4b84f3fe15073a2984ac30066 upstream.

Commit 2ee57d58735 ("dm cache: add passthrough mode") inadvertently
removed the deferred set reference that was taken in cache_map()'s
writethrough mode support. Restore taking this reference.

This issue was found with code inspection.
