wayland/cursor-surface: Update cursor on dispose

Browse Source 
Otherwise we'll have a cursor sprite backed by a surface that no longer
exist. This usually doesn't happen, but can happen in rare situations
related to pointer capability changes Wayland client cursor changes and
hotplugs.

Fixes the following crash:
