Improve NTLM authentication logging.

Browse source 
If only one side of a connection was seen, the ntlm.log
would indicate that the authentication failed.  This has been
modified so that the success is listed as null since it's not
known whether or not the authentication was successful.

It can be inferred from continued SMB analysis though because
activity will continue taking place.  I changed it though
because the log shouldn't assume more than what it sees.
