http2: do not append data after closing file

Ticket: #6211

Completes commit 02dece5db5170ae9bd946d0b8805e45ac071a97c

Once a http2 stream has end of stream flag, we close the file.
If we see new data frames with this stream id, the new_chunk
function should ignore them as the file was already closed.
