When a surface has a buffer at creation time we send an error, which results
in a disconnection and all resources being destroyed.
Since we send that error and return before performing the configure_list init
weston_desktop_xdg_surface_destroy() will walk an uninitialized list and
dereference a NULL pointer.
Initializing the list earlier prevents this from happening.
