[PATCH] dm: log: rename complete_resync_work
The complete_resync_work function only provides the ability to change an
out-of-sync region to in-sync. This patch enhances the function to allow us
to change the status from in-sync to out-of-sync as well, something that is
needed when a mirror write to one of the devices or an initial resync on a
given region fails.
