wifi: nl80211/cfg80211: Stop supporting cooked monitor

Unconditionally start to refuse creating cooked monitor interfaces to
phase them out.

There is no feature flag for drivers to opt-in for cooked monitor and
all known users are using/preferring the modern API since the hostapd
release 1.0 in May 2012.
