HTTP/2: don't send SETTINGS ACK before already queued DATA frames.

Previously, SETTINGS ACK was sent immediately upon receipt of SETTINGS
frame, before already queued DATA frames created using "old" SETTINGS.

This incorrect behavior was source of interoperability issues, because
peers rely on a fact that "new" SETTINGS are in effect after receiving
SETTINGS ACK.
