BUG/MINOR: mux-h1: Properly report EOI/ERROR on read0 in h1_rcv_pipe()

In h1_rcv_pipe(), only the end of stream was reported when a read0 was
detected. However, it is also important to report the end of input or an
error, depending on the message state. This patch does not fix any real
issue for now, but some others, specific to the 2.8, rely on it.

No backport needed.
