net: Convert hwsim_net_ops
These pernet_operations allocate and destroy IDA identifier, and these actions are synchronized by IDA subsystem locks. Exit method removes mac80211_hwsim_data enteries from the lists, and this is synchronized by hwsim_radio_lock with the rest parallel pernet_operations. Also it queues destroy_radio() work, and these work already may be executed in parallel with any pernet_operations (as it's a work :). So, we may mark these pernet_operations as async.
