compositor: Set pointer surface input region to empty on attach

We set up an emtpy region for the initial NULL-cursor, and then going
from no buffer to a 32x32 buffer didn't trigger the undeffing of the input
region.  So when something sets a cursor of a different size, the cursor
surface input region gets initialized and starts swallowing events.
