onscreen/native: Skip try_post_latest_swap if shutting down

Browse source 
Otherwise we could get:

  meta_kms_prepare_shutdown ->
  flush_callbacks ->
  ... ->
  try_post_latest_swap ->
  post and queue more callbacks

So later in shutdown those callbacks would trigger an assertion failure
in meta_kms_impl_device_atomic_finalize:

  g_hash_table_size (impl_device_atomic->page_flip_datas) == 0
