default_controls.js: Fix cursor setting init.

The rfb variable wasn't available at the point settingsDisabled() was
being called since it was called inline with RFB() initialization. To
solve this we pass the updateState rfb variable so that the canvas can
be queried for setting the cursor_uri value.
