crush/CrushWrapper: rebuild reverse maps after rebuilding crush map

The Objecter will crash when localized reads are enabled and two threads
attempt to rebuild the (invalidated) reverse maps concurrently. This
should address the issue for the Objecter use-case without the need to
add additional locking.

Fixes: https://tracker.ceph.com/issues/44311

(cherry picked from commit 8b866794f5b3674c5e3ad9adceb5e3230d55a0e0)
