wifi: iwlwifi: mvm: don't add default link in fw restart flow

When we add the vif (and its default link) in fw restart we may
override the link that already exists. We take care of this but if
link 0 is a valid MLO link, then we will re-create a default link on
mvmvif->link[0] and we'll loose the real link we had there.

In non-MLO, we need to re-create the default link upon the interface
creation, this is fine. In MLO, we'll just wait for change_vif_links()
to re-build the links.
