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.
