Yes, the energy level of $M {g}^{2 +}$ will be higher than that of $M {g}^{+}$. However, since Mg will form an ionic compound with an gaseous anion, the energy released from ionic bonding is enough to compensate for this extra ionisation energy calculated.
This means that forming a compound of $M g O$ will give out much more energy than forming $M g \left(2\right) O$, leading to greater stability.
