When an NHRP peer was forwarding a message, it was copying all extensions from the originally received packet. The authentication extension must be regenerated hop by hop per RFC2332. This fix checks for the auth extension when copying extensions and omits the original packet auth and instead regenerates a new auth extension. Fix bug #16507 Signed-off-by: Denys Haryachyy <garyachy@gmail.com> (cherry picked from commit 8e3c278)
