Recreate TextureView's display list on attach
Bug #9425270

When a TextureView is detached from its window and immediately
re-attached, the display list is not destroyed but reused as is.
TextureView will however destroy the layer and surface texture
reference by the display list.

The solution is to force TextureView to invalidate its display
list on re-attach if it previously had a surface/layer pair.
