In h2_send(), when something is sent, we remove the flags (H2_CF_MUX_MFULL|H2_CF_DEM_MROOM) on the h2 connection. This way, we are able to wake up all streams waiting to send data. Unfortunatly, these flags are unconditionally removed, even when nothing was sent. So if the h2c is blocked because the mux buffers are full and we are unable to send anything, all streams in the send_list are woken up for nothing. Now, we only remove these flags if at least a send succeeds. This patch must be backport to 2.0.
