reply_doserror() doesn't force DOS errors on the wire.

Start migrating uses of reply_doserror() to reply_nterror() with the
correct mapping. Eventually we'll get to the point where we can
change reply_doserror() to force a DOS error code on the wire,
and can change calls to reply_nterror(req, NT_STATUS_DOS()) - which *does*
force DOS errors on the wire - to reply_doserror(). Which might
actually make the server code look like it's making sense.
