computeResponseNTLMv2 crashed on av_pairs[NTLMSSP_AV_DNS_HOSTNAME][1] when that AV pair is absent

Now falls back to the NetBIOS computer name (NTLMSSP_AV_HOSTNAME), then to empty

Just out of curiousity: Where did you run into a host that does not populate the NTLMSSP_AV_DNS_HOSTNAME?

Hi @kost, I had the same question while trying to validate this PR: in which target/protocol/server configuration did you see NTLMSSP_AV_DNS_HOSTNAME missing from the NTLM Type 2 target info?

I tested against Windows DC services and Samba, and they all populated it, so any repro details would help.
