storage: remove spurious call to maybeInlineSideloadedRaftCommand

Entries are "thinned" only when passed to `r.append()` (i.e. written
to disk) and they are always returned "fat" from `Entries()` (i.e.
Raft's way to get entries from disk). Consequently Raft never sees
thin entries and won't ask us to commit them.

Touches cockroachdb#31618.

Release note: None
