Arne Welzel fbf9d53c44 HTTP: Reset reply_message for HTTP/0.9 ...

OSS-Fuzz tickled an assert when sending a HTTP response before a HTTP/0.9
request. Avoid this by resetting reply_message upon seeing a HTTP/0.9 request.

PCAP was generated artificially: Server sending a reply providing a
Content-Length. Because HTTP/0.9 processing would remove the ContentLine
support analyzer, more data was delivered to the HTTP_Message than
expected, triggering an assert.

This is a follow-up for zeek/zeek#2851.
