cifs: Add client version details to NTLM authenticate message

The NTLM authenticate message currently sets the NTLMSSP_NEGOTIATE_VERSION
flag but does not populate the VERSION structure. This commit fixes this
bug by ensuring that the flag is set and the version details are included
in the message.
