cfg80211: don't add p2p device while in RFKILL
Since P2P device doesn't have a netdev associated to it, we cannot prevent the user to start it when in RFKILL. So refuse to even add it when in RFKILL. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
