This patch is to simplify 'targetNode' function to return 'innerNode' rather than
old code introduced in 18736 at main, which didn't make sense: if a node is
disconnected, its parent element also has to be disconnected, which means
most of the logic in HitTestResult::targetNode was just dead code.

* Source/WebCore/rendering/HitTestResult.cpp:
(HitTestResult::targetNode): Deleted
* Source/WebCore/rendering/HitTestResult.h: Inlined 'targetNode' to return 'innerNode'
