When a key-value store corruption check happens immediately after a
compaction, the revision at which the key-value store hash is computed,
is the compacted revision itself.
In that case, the hash computation logic was incorrect because it
returned an ErrCompacted error; this error should instead be returned when
the revision at which the key-value store is hashed, is strictly lower
than the compacted revision.
Fixes#14325
