Call directly RenderBlock::deleteLineBoxTree

Reviewed by Darin Adler.

Instead of implementing RenderLineBoxList::deleteLineBoxTree logic inside
RenderBlock::determineStartPosition, we can reuse the code. The commentaries added
in the changeset #86628 are not valid anymore, nextRootBox is casting m_nextLineBox
and nextLineBox is returning m_nextLineBox.
