adw-carousel: Fix a -Wmaybe-uninitialized warning
It’s a false positive, but it’s better to be able to compile without warnings than having to remember which ones are false positives every time.
../../source/libadwaita/src/adw-carousel.c: In function ‘adw_carousel_reorder’:
../../source/libadwaita/src/adw-carousel.c:1324:5: error: ‘next_info’ may be used uninitialized [-Werror=maybe-uninitialized]
1324 | gtk_widget_insert_before (child, GTK_WIDGET (self), next_info->widget);
