BUG/MEDIUM: mux-h2: Never set SE_FL_EOS without SE_FL_EOI or SE_FL_ERROR

When end-of-stream is reported by a H2 stream, we must take care to also
report an error is end-of-input was not reported. Indeed, it is now
mandatory to set SE_FL_EOI or SE_FL_ERROR flags when SE_FL_EOS is set.

It is a 2.8-specific issue. No backport needed.
