If using --object-dir to point into a repo while the current
working dir is outside, such as

  git init /repo
  git -C /repo ... # add some objects
  cd /non-repo
  git multi-pack-index --object-dir /repo/.git/objects/ write

the binary will segfault trying to access the object-dir via
the repo it found, but that's not fully initialized. Fix it

OK, so write_midx_internal() was given an object_dir to work in,
made various changes to that directory, but at the very end of the
sequence, instead of clearing the revindex in the object_dir we have
been working in, cleared the odb associated with the repository.

I'm not sure I'd claim "cleared the odb" but it's also not entirely
clear to me what you mean by that.

"cleared the revindex in the wrong odb" is what I meant to say.
