batch delete: report an already-absent object as such

A delete run whose DELETE answered 6A88/6A82 is still a success (the
object is gone, the goal is met) but it is no longer reported as a plain
"OK": the attempt result is 'already_absent', the counts gain that
bucket ("Deleted: N - Already absent: M"), the verdict reads "Already
absent" and the notice says the card was already absent.  A reinstall's
tolerated pre-delete keeps the install outcome (the install is the
point).
