wifi: mac80211_hwsim: change hwsim_class to a const struct

Browse Source 
The class_create() call has been deprecated in favor of class_register()
as the driver core now allows for a struct class to be in read-only
memory. Change hwsim_class to be a const struct class and drop the
class_create() call.
