wlr_output_cursor: assert renderer isn't NULL
When a wlr_output add to wlr_output_layout, wlr_cursor will create wlr_buffer of xcursor for the wlr_output, this behavior depends wlr_renderer of wlr_output, using assert to ensure renderer is initialized before wlr_output_layout_add and wlr_cursor_set_buffer/ wlr_cursor_set_xcursor.
