wifi: iwlwifi: mvm: assign link STA ID lookups during restart

Browse Source 
When restarting the HW, mac80211 first adds the STA back with only one
link enabled. This means that iwl_mvm_alloc_sta_after_restart will not
see the other links and will not do the assignment.

As such, do the assignment when mac80211 is activating the link for the
station.
