DRI2: limit the swap rate when CRTC is in DPMS-off state
If drawable is displayed on a CRTC and relevant CRTC is in
DPMS off state, defer the swap by a fixed (hard-coded) time.
This patch fixes a bug that caused an application to render
at uncontrolled rate when CRTC goes into DPMS "off" state,
thus thrashing the GPU and CPU and likely offsetting the
power savings achieved by shutting off the display.
