When a dedup write fails, we try to roll the DDT entry back to a known good state. However, this also rolls the refcounts and the last-update time back to the state they were at when we started this write. This doesn't appear to be able to cause any refcount leaks (after the fix in 17123). This PR prevents that from happening by only rolling back the parts of the DDT entry that have been updated by the write so far. Sponsored-by: iXsystems, Inc. Sponsored-by: Klara, Inc.
