wayland/surface: Clear texture when attaching NULL

Browse Source 
When 252e64a0eae61735a912d41817c6e6f24824146b moved the texture
ownership to MetaWaylandSurface, it failed to handle the case when a
NULL-buffer is attached, leaving the texture reference in place. This
caused issues when the surface should have been hidden (e.g. attaching a
NULL buffer to a cursor surface for hiding the cursor sprite).
