No hw keys are ever uploaded for scanning/roc links and the link remove
path already skips the key iteration for them. The add path still runs
it, and since mt7996_set_hw_key() resolves the target through
mvif->link[link_id] rather than the offchannel link, starting a scan on
another band re-uploads the group keys of the link sharing the same
link_id, re-sending its BSS cipher info and, for BIGTK with beacon
protection on an AP link, toggling its beacons off and on.
Skip the key iteration for offchannel links, mirroring the remove path.
