[PATCH] wayland: unmap popup along with its toplevel

If an application umaps the toplevel from its popup callback, this can
lead to a protocol error.

Make sure we mark popup parent and use that to check if their parent is
the toplevel being unmapped in which case we shall unmap the popup first
to avoid the protocol error.
