As a follow up from https://bugs.webkit.org/show_bug.cgi?id=120397, make RenderRegion::generatingElement() return a reference instead of pointer since for regions, generatingNode cannot return 0.
RenderRegionSet derives from RenderRegion.
Is generatingElement() always not NULL for RenderRegionSet as well? I'm thinking not.

At this moment, RenderMultiColumnSet -> RenderRegionSet -> RenderRegion and RenderMultiColumnSet is created as an anonymous block. Therefore, for this type of region, generatingElement() can return NULL.
Closing this bug as invalid.
