When a window is being closed, the frame_done callback often runs after
the output is already destroyed, i.e:
wayland_output_start_repaint_loop
input_handle_button
wayland_output_destroy
frame_done
To fix this, destroy the callback before destroying the output.
(Also, fix the type of output in frame_done: it's passed in
a wayland_output, not a weston_output.)
