s3:smbd: unimplement FSCTL_VALIDATE_NEGOTIATE_INFO with "server max protocol = SMB2_02"

A client that supports SMB3 will do a signed FSCTL_VALIDATE_NEGOTIATE_INFO
after a tree connect. This FSCTL_VALIDATE_NEGOTIATE_INFO call contains
the client capabilities, client guid, security mode and the array of supported
dialects. But if SMB 2.02 is negotiated the doesn't send these values to the
server in the first connection attempt (when the client starts with a SMB1 Negotiate).

Windows servers that only support SMB2 just return NT_STATUS_FILE_CLOSED
as answer to FSCTL_VALIDATE_NEGOTIATE_INFO.

We should do the same if we just pretend to support SMB 2.02,
as SMB 2.10 always include an SMB2 Negotiate request we can leave it as is.
