BUG/MINOR: mux-h1: Be sure to only set CO_RFL_READ_ONCE for the first read

Browse Source 
The condition to set CO_RFL_READ_ONCE flag is not really accurate. We must check
the request state on frontend connection only and, in the opposite, the response
state on backend connection only. Only the parsed side must be considered, not
the opposite one.

This patch must be backported to 2.2.
