cfg80211: add add_nan_func / del_nan_func

Browse Source 
A NAN function can be either publish, subscribe or follow
up. Make all the necessary verifications and just pass the
request to the driver.
Allow the user space application that starts NAN to
forbid any other socket to add or remove functions.
