http: fix error message when specifying headerTimeout for createServer

This change fixes the message on the error received when calling
http.createServer(...) with a header timeout greater than the request
timeout is incorrect.

The validation requires that the header timeout is lower than the
request timeout, but the error message asks for the opposite.
