wayland: Warn when an application tries to map popup incorrectly

When a popup is mapped but will not be the top most popup (for example
the parent is not the current top most popup, or if there already is a
popup mapped but the parent is a toplevel), warn and ignore it instead
of continuing, as continuing would be a protocol violation.
