If the server got incomplete headers (I was able to reliably trigger this with connection reuse), the reqstate variable was still incremented.

This resulted in the request state becoming inconsistent - notably, for master, we saw HEAD requests believed they always included a checksum. There are likely other strange XrdHttp behaviors that could have been triggered due to the same bug, hence the request for backport to the stable branch.

(cherry picked from commit 88dad6a; backport of relevant fix in #822)
