<pre>[SVG -> OTF Converter] Crash when trying to re-convert a previously-failed font conversion
https://bugs.webkit.org/show_bug.cgi?id=156175
<rdar://problem/25130547>
Reviewed by David Kilzer.
m_externalSVGFontElement points inside the document owned by m_externalSVGDocument.
However, when the m_externalSVGDocument is destroyed (due to a failed conversion),
we weren't resetting m_externalSVGFontElement. Then, when trying to re-convert, we
were using the fact that m_externalSVGFontElement is non-null to mean it's valid.
Test: fast/text/svg-font-invalid-glyph-path-failure.html (Under GuardMalloc)
* loader/cache/CachedSVGFont.cpp:
(WebCore::CachedSVGFont::ensureCustomFontData):</pre>
