[PATCH] desktop-shell: fix bug referencing invalid surface list

[Ryo Munakata]

In shell_destroy_shell_surface, we remove the link of a shell_surface.
There is a case which the link references shell_client::surface_list
which is already free'd.
Therefore we have to remove shell_client::surface_list when freeing
a shell_client.
