_http_common ParserIncomingMessage fails to check for undefined on parser.socket.server[kIncomingMessage]

[nyxtom]

node/lib/_http_common.js

Lines 78 to 82 in 15e41a9

	var ParserIncomingMessage = parser.socket && parser.socket.server ?
	parser.socket.server[kIncomingMessage] : IncomingMessage;
	parser.incoming = new ParserIncomingMessage(parser.socket);
	parser.incoming.httpVersionMajor = versionMajor;

Due to this line of code, if parser.socket.server[kIncomingMessage] is undefined, an error will be thrown on the line below where the ParserIncomingMessage is constructed. A simple additional check here would solve this issue. A few libraries have cropped this up in socket.io, ws and some others that weren't happening in previous versions of node.

Node version: 9.6.0
Platform: OSX

This will be in the 10.0.0 release. See #20029 for a fix.
