Fix bug #9329 - Directory listing with SeBackup can crash smbd.
When we do a become_root()/unbecome_root() pair to temporarily
raise privilege, this NULLs out the NT token. If we're within
a become_root()/unbecome_root() pair then return the previous
token on the stack as our NT token. This is what we should be
using to check against NT ACLs in the file server. This copes
with security context changing when removing a file on close
under the context of another user (when 2 users have a file
open, one sets delete on close and then the other user has
to actually do the delete).
