HTTP/2: fixed a segfault while processing unbuffered upload.

The ngx_http_v2_finalize_connection() closes current stream, but that is an
invalid operation while processing unbuffered upload.  This results in access
to already freed memory, since the upstream module sets a cleanup handler that
also finalizes the request.
