Fix bmcweb core-dump caused by Split up authenticate

Ed changed the code from req.emplace(parser->release()) to
req.reset() in line 728 of the http/http_connection.hpp file in this
patch https://gerrit.openbmc-project.xyz/c/openbmc/bmcweb/+/47122.
So req cannot be used in doReadHeaders(). These codes are not necessary,
so I choose to delete them.

Tested:
1. Keep these codes and set bmcweb-logging=enabled, then log in to
bmcweb using webui. Bmcweb will core-dump.
2. Delete these codes, bmcweb works normally.
