Wayland: Fix map before XDG decoration configure

Browse Source 
If the xdg_toplevel has a decoration, we need to wait for its first
configure event as well before we are allowed to attach the first
buffer.

It seems racy to assume that this will always happen inside the first
surface configure sequence, so this commit makes that condition
explicit.  This may turn out to have been overly defensive.
