wifi: iwlwifi: mvm: fix iwl_mvm_mac_flush_sta()
When I implemented iwl_mvm_mac_flush_sta() I completely botched it;
it basically always happens after the iwl_mvm_sta_pre_rcu_remove()
call, and that already clears mvm->fw_id_to_mac_id[] entries, so we
cannot rely on those at iwl_mvm_mac_flush_sta() time. This means it
never did anything.
Fix this by just going through the station IDs and now with the new
API for iwl_mvm_flush_sta(), call those.
Fixes: a6cc6ccb1c8a ("wifi: iwlwifi: mvm: support new flush_sta method")
