wifi: iwlwifi: mvm: add an indication that the new MLD API is used

WE can't mix between the new MLD API and the old API.
I.e. - we can't send one of the new cmds and then one of the old ones.
This will cause a FW assert. So we need an indication what API should be
used. We use the new API if:
1. FW supports it
2. We are registered to mac80211 with the new MLD ops
Add an indication which will only be true if both conditions are true.
