dix: fix crash on shutdown if a disabled device is still grabbed (XI1 grab)
A disabled device doesn't have a sprite (less so a sprite->win) and triggers a NULL-pointer dereference on shutdown when all active grabs are released as part of the cleanup. Fix this by checking for sprite being non-null and setting the focus window to the NullWindow if it is. The rest of the patch just attempts to make things more readable.
