cifs: track the flavor of the NEGOTIATE reponse
Track what sort of NEGOTIATE response we get from the server, as that
will govern what sort of authentication types this socket will support.
There are three possibilities:
LANMAN: server sent legacy LANMAN-type response
UNENCAP: server sent a newer-style response, but extended security bit
wasn't set. This socket will only support unencapsulated auth types.
EXTENDED: server sent a newer-style response with the extended security
bit set. This is necessary to support krb5 and ntlmssp auth types.
