Jonas Ådahl 867494d3df wayland/cursor-surface: Update cursor on dispose
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:

  #0 meta_wayland_buffer_get_resource() at ../src/wayland/meta-wayland-buffer.c:128
  #1 realize_cursor_sprite_from_wl_buffer_for_gpu() at ../src/backends/native/meta-cursor-renderer-native.c:1649
