BUG/MINOR: mux-h1: Use the right variable to set NEGO_FF_FL_EXACT_SIZE flag

Instead of setting this flag on the ones used for the zero-copy negociation,
it is set on the connection flags used for xprt->rcv_buf()
call. Fortunately, there is no real consequence. The only visible effect is
the chunk size that is written on 8 bytes for no reason.

This patch is related to issue #2598. It must be backported to 3.0.
