Slow HTTP/2 download speed per connection

curl/libcurl download speed from HTTP/2 servers seems to be limited
to ~1.5MiB/s per connection.

I tested on localhost both:
* h2o(Both TLS and plain).
* nghttpd(only TLS, --no-tls seems broken).

nghttp works as expected. So, the bug seems to be in libcurl.

Latest GIT versions of curl and nghttp2 are used in
a GNU/Linux x86_64 system.
