fix(dracut-catimages.sh): drop unused dwarning function

shellcheck complains about SC2317 (info): Command appears to be
unreachable. Check usage (or ignore if invoked indirectly).

The function `dwarning` is not called in `dracut-catimages.sh`. So drop
this unused function. It can be re-introduced once it is needed.
