    wifi: iwlwifi: mvm: use correct key iteration
    
    [ Upstream commit 4f1591d292277eec51d027405a92f0d4ef5e299e ]
    
    In the cases changed here, key iteration isn't done from
    an RCU critical section, but rather using the wiphy lock
    as protection. Therefore, just use ieee80211_iter_keys().
    The link switch case can therefore also use sync commands.
