Alternative to7bf08afwhich was reverted in the previous commit.7bf08affixed the problem that layer-shell clients are terminated when it's unmapped, by sending configure events in node-destroy handler rather than in unmap handler. But it caused a UAF bug when an output with layer-shell clients is destroyed. So this patch fixes the original issue by simply skipping the surface in arrange_one_layer() if it's being unmapped.
