wayland/legacy-xdg-shell: Handle requests after toplevel was unmanaged

Browse Source 
As with xdg-toplevel proper, a legacy xdg-toplevel can be unmanaged by
the compositor without the client knowing about it, meaning the client
may still send updates and make requests. Handle this gracefully by
ignoring them. The client needs to reassign the surface the legacy
xdg-toplevel role again, if it wants to remap the same surface, meaning
all state would be reset anyway.

Closes: https://gitlab.gnome.org/GNOME/mutter/issues/240
(cherry picked from commit 64df627688)
