osd/ReplicatedPG: Set data/omap digest after promote object.

For promote object from base tier, set data/omap digest if src have
data/omap content.
BTW, because considering performance we modify content don't recalc
data/omap digest(in some case we should reread all data), so maybe the
src don't have data/omap digest. But we don't care this.
