Well rd hint for when we provide a structure, that code right now
disregards when initiator == USER, and this works well only for
when the driver sending the rd struct hint also only registered
to cfg80211 the channels its legally capable of. If a driver
which does not use reg_notifier() and registers *all* of its channels
uses this then the USER set regdom will be used and *all* channels
will be left intact.
