Peter Hutterer ef33d433d1 Xi: disallow grabbing disabled devices 
Grabbing a disabled (pointer) device will lead to a segfault later
in the myriad of places where we look at the device's spriteInfo - which
will be NULL.

As a workaround, disallow grabbing a disabled device by pretending it's
already grabbed. Since the point of a grab is to receive all events by
that device and disabled devices cannot send events, this should be Good
Enough.
