Xi: fix logic error when calculating emulated motion events

Browse source 
gcc -Wlogical-op
exevents.c: In function 'DeliverEmulatedMotionEvent':
exevents.c:1480:13: warning: logical 'or' of collectively exhaustive
tests is always true [-Wlogical-op]

The relevant snippet of exevents.c:

1479         if (ti->listeners[0].type != LISTENER_POINTER_REGULAR ||
1480             ti->listeners[0].type != LISTENER_POINTER_GRAB)
1481             return;

This condition was always true, causing dropped motion events.
