osd: check that source OSD is valid for MOSDRepScrub

Make sure the message we got from the peer OSD is valid.  Specifically,
this avoids a race like this:

- A marks down B
- B sends MOSDRepScrub
- A accepts connection from B as new
- A replies to scrub
- B crashes because msgr seq 1 < expected seq 1000+

See #8880 for the most recent fix for requests.

Fixes: #9555
Backport: giant, firefly
