Fix bug introduced by 18691642931e5c7ac8af83ac3a84fbcb36000f96. #493
Don't pass unitialized name and namelen values to nghttp2_submit_request.
I'm having a bit of a hard time understanding the test infrastructure but running this command:
valgrind curl --http2 --insecure -H "Connection: keep-alive" https://http2.akamai.com/demo
Produces the following output before the fix (it's clean afterwards):
==22582== Memcheck, a memory error detector
