Fix server crash when a client dies during a drag with an icon

Browse source 
If a client dies during a drag that it started using an icon surface,
the server could crash because the icon surface is not valid anymore.

Fix this by using a destroy listener to reset device->drag_surface to
nil when the surface is destroyed.
