nl80211: Do not change iftype for static AP interface

Browse Source 
Some devices have limitations which do not allow changing virtual
interface mode from AP to station or vice versa. To work around this,
check if such AP interface is not dynamic. If such an interface is
enumarated, just set ifmode to AP and avoid setting nlmode to default
station mode on deinit.
