Fix wrong comments in DragResizeInputListener

Geometry updates were used to signal a complete cycle of resize
handling, and the readiness of taking the next batch of input events for
handling. However, it's not guaranteed there will be a gemoetry update
for all input events we handle, so we changed the way we handle batched
input events to be Choreographer based, but we left the incorrect
comment until now.
