Instead of just guarding null access, this change make DocumentType to 
have non-null m_document.  
This should be more safe to guarantee non-null m_document than just gurding
null access to it.
This is because DocumenType is a subclass of Node and certain part of codebase
assumes
Node::m_document non-null.
