BUG/MEDIUM: h1: Really skip all updates when incomplete messages are parsed

In h1_headers_to_hdr_list, when an incomplete message is parsed, all updates
must be skipped until the end of the message is found. Then the parsing is
restarted from the beginning. But not all updates were skipped, leading to
invalid rewritting or segfault.

No backport is needed.
