[PATCH] dix: free default colormap before screen deletion

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

If we don't free this here, it gets freed later in the resource
cleanups, however it then looks up up pmap->pScreen, which we
freed already in this function. So free the default colormap
when we should.

This fixes a bug after a couple of hotplug cycles when you try
to exit the X server and it crashes.
