If the element associated with the SVGLength is in an inactive document,
there'll be no layout, so renderStyleForLengthResolving() will be able
to exit the loop without finding a RenderStyle to return.

* Source/WebCore/svg/SVGLengthContext.cpp:
(renderStyleForLengthResolving): Remove 'ASSERT_NOT_REACHED'
* LayoutTests/svg/dom/SVGLength-value-in-inactive-document.html: Add Test Case
* LayoutTests/svg/dom/SVGLength-value-in-inactive-document-expected.txt: Add Test Case Expectation
