OPTIM: proto_http: don't enable quick-ack on empty buffers

Commit 5e205524 was a bit overzealous by inconditionally enabling
quick ack when a request is not yet in the buffer, because it also
does so when nothing has been received yet, causing a useless ACK
to be emitted.

Improve the situation by doing this only if the input buffer is
empty (indicating that nothing was sent by the client).

In case of keep-alive, an empty buffer means we already have a
response in flight which will serve as an ACK.
