smbd: fix initial large PAC sess setup response

smbd: fix initial large PAC sess setup response

An oversize Kerberos security token may be split across multiple Session
Setup AndX requests when authenticating as a user who is a member of
many (~2000) groups.
In such a case the NativeOS, NativeLanMan & PrimaryDomain fields must be
sent with the NT_STATUS_MORE_PROCESSING_REQUIRED response. Otherwise
Windows clients may resend the same security token data in subsequent
session setup andX requests, as observed with Windows 7 and Server 2012.

This change fixes the SMB1 server only.

Fix bug #9658 - Session Setup AndX exchange fails with an oversize security
token.
