BUG/MINOR: http-ana: Handle L7 retries on refused early data before K/A aborts

When a network error occurred on the server side, if it is not the first
request (in case of keep-alive), nothing is returned to the client and its
connexion is closed to be sure it may retry. However L7 retries on refused
early data (0rtt-rejected) must be performed first.

In addition, such L7 retries must also be performed before incrementing the
failed responses counter.

This patch must be backported as far as 2.0.
