[PATCH] Doc: no midx and partial clone relation

The multi-pack index treats promisor packfiles (that is, packfiles that
have an accompanying .promisor file) the same as other packfiles. Remove
a section in the documentation that seems to indicate otherwise.

Stolee, can you check if my understanding is correct?

To my recollection, midx does not treat promisor packfiles specially,
and searching for "promisor" in midx.c seems to support that (the only
results are relating to selection of commits for midx bitmap creation).
