BUG/MINOR: stream: Decrement server current session counter on L7 retry
When a L7 retry is performed, we must not forget to decrement the current
session counter of the assigned server. Of course, it must only be done if
the current session is already counted on the server, thus if SF_CURR_SESS
flag is set on the stream.
This patch is related to the issue #1003. It must be backported as far as
2.0.
