osd/scrub: stop sending bogus digest-update event messages

A minimal change extracted from PR#44050, to facilitate
backporting.

The multitudes of bogus events generated fill up the logs.

Signed-off-by: Ronen Friedman <rfriedma@redhat.com>
(cherry picked from commit e1b5347b81d17c8a5a1f6e1d4d76d18977ec2b0c)
Conflicts: the logic changes were already part of Quincy. Left is
  a removal of an unneeded log message.
