wifi: mac80211: don't allow link changes when iface is down
ieee80211_set_active_links() only checks that the interface is running in
the inner __ieee80211_set_active_links(), after drv_can_activate_links()
was already called, so using active_links on an interface that's down
triggers the check-sdata-in-driver warning.
Add the missing check in the debugfs file.
