BUG/MINOR: mux-h2: don't check the CS count in h2c_bck_handle_headers()
This function handles response HEADERS frames, it is not responsible
for creating new streams thus it must not check if we've reached the
stream count limit, otherwise it could lead to some undesired pauses
which bring no benefit.
This must be backported to 1.9.
