MRP-2021 mdd: credits for changelog calculation

Changelog record addition may require object creation and rename, and
writing 4 records each up to 2 blocks long, while only 16 credits are
reserved (or 14 when quota is off).
Reserve space for the operation so that it was enough for all the
suboperations.
