Peter Hutterer 4b7f00346d 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.
