cfg80211: make regulatory_request use wiphy_idx instead of wiphy
We do this so later on we can move the pending requests onto a workqueue. By using the wiphy_idx instead of the wiphy we can later easily check if the wiphy has disappeared or not. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
