[PATCH 3/8] mka: fix length when encoding SAK-use

[Sabrina Dubroca]

The room we actually use is length. This could also mess up the
receiver, since it will advance by the actual length (as indicated by
the parameter body's length), which could differ from the offset at
which we stored the next item.
