Remove early call to DidResizeOrRepaintAck()

Previously, we would defer commit when the child didn't yet have a
LocalSurfaceId. This meant we needed a special case to call
DidResizeOrRepaintAck() early when commit would be deferred.

But now the child has the ability to allocate its own
LocalSurfaceId. As a result, we no longer need to defer commit. And
thus, no longer need to call DidResizeOrRepaintAck() early.
