MINOR: mux-h2: Set known input payload length of the sedesc

Browse Source 
Set <kip> value when data are transfer to the upper layer, in h2_rcv_buf().
The new <body_len> filed of the H2S is used to increment <kip> value and
then it is reset. The patch relies on the previous one ("MINOR: mux-h2: Save
the known length of the payload").
