wifi: mac80211: Drop cooked monitor support

Hostapd switched from cooked monitor interfaces to nl80211 Dec 2011.
Drop support for the outdated cooked monitor interfaces and fix
creating the virtual monitor interfaces in the following cases:

 1) We have one non-monitor and one monitor interface with
    %MONITOR_FLAG_ACTIVE enabled and then delete the non-monitor
    interface.

 2) We only have monitor interfaces enabled on resume while at least one
    has %MONITOR_FLAG_ACTIVE set.
