[PATCH v2 2/6] dxgi: Set the frame latency even when increasing the frame latency.

[Giovanni Mascellani]

From: Giovanni Mascellani

This is only partially correct, because the frame latency waitable
should be a semaphore instead. However, it's a step in the right
direction, in preparation to make the waitable an actual semaphore.
