LOK: Do not try to show an "update links" dialog

In commit f8528cdda9 (LOK: don't crash
when trying to show a dialog during file load, 2024-12-26), all not
yet async / not properly set up dialogs made to fail gracefully. In
the follow-up https://gerrit.libreoffice.org/c/core/+/180334, an
assert is added to still fail in debug builds.

The specific "update links" dialog case, that triggered the original
change in the first place, does not need to appear at all in the LOK
case, because there is no external documents available for updating.
This change avoids the dialog in that case.
