inhibit-shortcuts-dialog: Fix use-after-free

We have no dialog, and use muffin's default 'allow' - any window
that requests, can inhibit shortcuts in Wayland sessions (the same
as x11).

We destroyed the default object in the response callback, so we
can't try to hide it after the emission in
meta_inhibit_shortcuts_dialog_response().

Remove the warning declaring we have no dialog also.
