hwsim_netgroup counter is declarated as int, and it is incremented every time a new net is created. After sizeof(int) net are created, it will overflow, and different net namespaces will have the same identifier. This patch fixes the problem by introducing IDA instead of int counter. IDA guarantees, all the net namespaces have the uniq identifier. Note, that after we do ida_simple_remove() in hwsim_exit_net(), and we destroy the ID, later there may be executed destroy_radio() from the workqueue. But destroy_radio() does not use the ID, so it's OK. Out of bounds of this patch, just as a report to wireless subsystem maintainer, destroy_radio() increaments hwsim_radios_generation without hwsim_radio_lock, so this may need one more patch to fix.
