[PATCH AUTOSEL 6.6 044/139] 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.
