  REGRESSION(274689 at main): [GTK][Debug] Triggers assert on WOFF2 tests
https://bugs.webkit.org/show_bug.cgi?id=270414

Reviewed by Michael Catanzaro.

The convertWOFFToSfntIfNecessary() function can set the buffer to nullptr, specially if the
woff2::ConvertWOFF2ToTTF() call in convertWOFFToSfnt() fails. This patch re-introduces the buffer
check that was removed in 274689 at main.
