Bug 96863: REGRESSION(r124168): Null crash in RenderLayer::createScrollbar

This test PASSED if it didn't CRASH or ASSERT.
REGRESSION(r124168): Null crash in RenderLayer::createScrollbar https://bugs.webkit.org/show_bug.cgi?id=96863 Reviewed by Abhishek Arya. Source/WebCore: After r124168, we synchronously create any overflow:scroll scrollbar on the first style change - we used to wait until layout was called. The issue is that the logic in RenderLayer assumes that our node is completely attached when the style change is dispatched. The crash occured because the 'content' image code path in RenderObject::createObject triggered a style change too early. Test: scrollbars/scrollbar-content-crash.html * rendering/RenderObject.cpp: (WebCore::RenderObject::createObject): We need a style associated with the new RenderImage to call setImageResource but we don't need to trigger a style change. LayoutTests: * scrollbars/scrollbar-content-crash-expected.txt: Added. * scrollbars/scrollbar-content-crash.html: Added.
