dolphinstatusbar: Fix negative value warnings with small statusbar fixedwidth

During splitview animations the parentWidget()->width could be lower
than scrollbarWidth. If it goes to negatives it causes a lot of
warnings.

Make sure to bound the value between 0 and parentWidget()->width() so
that it can't go into negatives.
